Statistical Analysis of Experimental Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
All experimental data were represented as the mean ± standard deviation through at least three experiments. One‐way analysis of variance statistical method was used to analyze the experimental results through IBM SPSS Statistic 25 software (IBM, Armonk, NY). A p value of 0.05 was selected as a significance level, and the data were indicated with (*) for p < 0.05, (**) for p < 0.01, and (***) for p < 0.001, respectively. Full experimental details can be seen in the Supporting Information.

Implant Insertion Mode and Template Comparison

A statistical analysis was carried out with SPSS Statistic 25 (IBM Corporation, Armonk, New York, USA). The mean values and their standard deviations as well as the median values were computed. The Shapiro-Wilk and Kolmogorov-Smirnoff tests were used to test for a normal distribution. For the comparison of the implant insertion mode, the Mann-Whitney test was applied, and for the comparison of the templates, the Kruskal-Wallis test was applied. Statistical significance was set at α = 0.05. For the exact statistical significance, a Bonferroni adjustment was performed.

Statistical analyses were performed by using IBM SPSS Statistic 25 software (IBM Corporation) at the University of Pecs, Institute of Bioanalysis (performed by NF). The total sample size (n) was 76. Comparisons were made between serum and cytokine levels detected for the four study groups according to the non-parametric Kruskal-Wallis test with Bonferroni post hoc test. To examine the relationship between cytokine levels and serum parameters, Spearman’s rank correlation coefficient was applied. Mean data are reported ± standard deviation (SD). Statistical significance was set at *p < 0.05, or **p < 0.01.

Statistical analysis was performed with unpaired Student’s t-test for pairwise comparisons in SigmaPlot version 12.5 software (Systat Software Inc. Washington, USA) or one-way analysis of variance (ANOVA) with a Bonferroni post-test for multiple comparisons and using Kaplan-Meier method and a log-rank test (survival) and Mann-Whitney U test (body weight) in IBM SPSS Statistic 25 software (IBM. NY, USA). A P-values less than 0.05 were considered to be statistically significant. The data were presented as the means ± SD or SEM of three independent experiments.

Statistical Analysis Methods for Metabolic Traits

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical tests were performed using the IBM SPSS Statistic 25 software (IBM Corp., Armok, NY, USA). Normal distribution of variables included in this study was checked prior statistical analyses and logarithmically transformed to achieve approximate normal distribution. Differences in mRNA expression between vis and sc AT were assessed using the paired Student’s t-test. Unpaired t-Test was used to analyze differences in adipose tissue mRNA expression among the groups. Logistic regression analyses have been conducted for the association of the SNP and the obesity/diabetes status. Linear regression analyses were used to assess the relationship between genetic variants/mRNA expression levels and quantitative metabolic traits. Pearson’s correlation analyses were conducted using two-way bivariate correlations. The additive model (with genotypes coded to 0, 1, and 2) was used, and if not stated otherwise, all p-values are adjusted for age, sex, and BMI. Two-sided p-values ≤ 0.05 were considered to provide evidence for nominal association and are presented without correction for multiple hypothesis testing.

Statistical Analysis of Experimental Data

For all experiments with the exception of RT-qPCR, linear raw data were first log transformed and then analyzed by a blocked (“experiment” and “treatment”) Student’s t-Test or one-way ANOVA with Dunnett’s post hoc test with “Experiment” being the blocking factor. For qRT-PCR analysis, 2ΔΔCt values were used in the same test. Data were obtained from at least three independent experiments and graphically represented as mean ± standard error of the mean (SEM). All statistical analyses were performed using SPSS statistic 25 (IBM, SPSS Inc., Chicago, IL, USA) and p-values < 0.05 were considered significant. Prism 8 (GraphPad Software, San Diego, CA, USA) was used to plot all data with control condition normalized to 100%. Graphical abstract was created with BioRender (Toronto, ON, Canada, agreement number; HX24FPAASI).

Evaluating Diabetic Macular Edema Patterns

The normal data distribution was tested using the one-sample Kolmogorov–Smirnov test. All continuous variables were expressed as mean ± standard deviation, while categorical variables as frequency and percentage. T test and Mann–Whitney test were performed as appropriate. Contingency tables (chi-square test) were used to investigate the relationship between pre- and post-recurrence DME pattern and between baseline DME pattern and pre- and post-recurrence morphological parameters (ELM and IS/OS). A one-way repeated measures analysis of variance (ANOVA) for each group was conducted to evaluate the null hypothesis that there is no change in functional and morphological parameter values when measured at baseline, maximal answer, and after recurrence in study groups. Post hoc tests were performed using the Bonferroni correction. Statistical evaluation was performed using SPSS (IBM SPSS Statistic 25). A p value < 0.05 was considered statistically significant.

Reproductive Strategies Across Ploidy Levels

All data were tested for their normality distribution by Kolmogorov-Smirnov and Shapiro-Wisk test and for their homogeneity of variance with the Levene test. Female development, seed set, reproduction pathway of seed formation, and pollen viability were determined per flower as a percentage and subsequently averaged per plants. The percentage of data were arcsine transformed before statistical analysis. We tested the influence of treatment on mean sexual ovules and seed set among ploidies with General Linear Model (GLM) univariate (Two-way ANOVA) for completely randomized factorial design model, and means were compared according to the least significant difference (LSD) test at 0.05 probability level (p-value < 0.05). Tukey HSD was performed to the means of sexual ovules to determine the main factors. Nonparametric Kruskal-Wallis and Mann-Whitney U-test were applied to test the influence of treatment on sexual seed formation per ploidy. Boxplots were plotted with untransformed percentage values and show the 25th, and 75th percentile ranges as a box, and the median as a black line: circles are outliers; asterisks are extreme values. All statistical analyses were performed with IBM SPSS Statistic 25 (IBM Deutschland GmbH).

Statistical analyses were carried out with IBM SPSS statistic 25 software. In human study Mann-Whitney U test was used to compare the variables in different groups and Wilcoxon signed-rank test to compare the variables within the same groups. T-test was used in mouse study. P-values less than 0.05 were considered significant (* p < 0.05, ** p < 0.01, *** p < 0.001).

All values were expressed as Mean ± S.E.M. (standard error of means). The data were analyzed and plotted using IBM SPSS Statistic 25 and GraphPad Prism 9. The normality test was conducted in IBM SPSS Statistic 25; all data were normally distributed. Multiple comparisons of data were performed with GraphPad Prism 9. Multiple groups were compared by one-way ANOVA followed by the Bonferroni post-hoc test. The statistical significance was defined as follows: *p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001; ****p ≤ 0.0001; *p ≤ 0.05 was considered statistically significant.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
