Statistical Analysis of Survival and Immune Responses

Check if the same lab product or an alternative is used in the 5 most similar protocols
GraphPad Prism V.7 for Windows (https://www.graphpad.com/) was used for all graphing and statistical analyses. Survival curves were determined by the Kaplan-Meier method, and differences between groups were queried using the log-rank Mantel-Cox test. Immune response data, which involved one variable, were assessed by one-way analysis of variance (ANOVA) with Tukey’s multiple comparisons test. Resazurin dye-based data, which involved two variables, were assessed by two-way ANOVA with Tukey’s multiple comparisons test. All reported p values were two-sided and were considered significant at a p value of ≤0.05. Graphs show means and SEs.

Statistical analysis was performed using GraphPad Prism v7 for Windows (San Diego). A significance level of p ≤ 0.05 was used for analysis of variance, implemented using the Kruskal–Wallis test followed by the Tukey’s post hoc test (p ≤ 0.05). Correlation between different parameters was performed at significance level of p ≤ 0.05.

Statistical Analysis of Experimental Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
GraphPad Prism v7 for Windows (GraphPad, San Diego, CA) was used for statistical analysis. A student t test was used for the comparison of a normally distributed continuous variable between 2 groups. Differences between several groups were compared by the nonparametric Wilcoxon rank-sum or Mann-Whitney test because of the small sample sizes for some experiments. The Mantel Cox text was used to compare survival curves for different groups on univariate analyses. All analyses were 2 sided, and values of P<0.05 were considered statistically significant.

Statistical Analysis of Quantitative and Qualitative Variables

Differences in quantitative variables were analysed by the Mann-Whitney U-test when comparing two groups and by Kruskal-Wallis with Dunn’s post-test correction when comparing multiple groups. χ2 test with Yates’ correction when required or Fisher’s exact test when appropriate were used to evaluate associations of qualitative variables in the different groups. Spearman’s rank analysis was performed for non-parametric variable correlations. All the statistical analyses were performed using GraphPad Prism V.7 for Windows (GraphPad Software, USA).

Statistical Analysis of Tumor Growth

Check if the same lab product or an alternative is used in the 5 most similar protocols
All statistical analyses were performed using GraphPad Prism V.7 for Windows (GraphPad Software, La Jolla, CA, USA). Analysis of tumor growth curves was conducted using two-way analysis of variance (ANOVA). Statistical differences between two sets of data were determined through a two-tailed Student’s t-test, while one-way ANOVA with Tukey’s post hoc test was used to determine statistical differences among three or more sets of data. Statistical differences between survival plots were determined using Log-rank (Mantel-Cox) test. Error bars represent SEM where noted. Asterisks indicate that the experimental p value is statistically significantly different from the associated controls at * p ≤ 0.05; ** p ≤ 0.01; *** p ≤ 0.001, **** p ≤ 0.0001.

Tumor Growth Curve Statistical Analysis

Statistical analysis of tumor growth curves was conducted using two-way analysis of variance (ANOVA). Two-tailed Student’s t-test was used to determine statistical difference between two sets of data while one-way ANOVA with Tukey’s post hoc test was used to determine statistical differences among three or more sets of data. Pearson r scores and p values (two tailed) were calculated for correlation data. All statistical analyses were performed using GraphPad Prism V.7 for Windows (GraphPad Software, La Jolla, CA, www.graphpad.com). Error bars represent SD. Asterisks indicate that the experimental p value is statistically significantly different from the associated controls at *p≤0.05; **p≤0.01; ***p≤0.001, ****p≤0.0001.

Transcriptomic Analysis of Gene Expression

Transcriptomic data were analyzed by pairwise comparisons using a Welch t test on the log-transformed gene expression data. The effect of a factor was considered to be significant with a p value < 0.05. All analyses and graphical figures were made using R software v3.1.1 [75 ], as well as GraphPad Prism v7 for Windows, GraphPad Software, La Jolla California USA, www.graphpad.com. Graphical figures represent the mean of all replicates for each point. Error bars represent the standard error calculated as σ/√n, where σ is the standard deviation and n is the number of replicates.

Hierarchical Clustering of Gene Expression Profiles

Check if the same lab product or an alternative is used in the 5 most similar protocols
Normalized expression data were Log 2 transformed and loaded into the Gene-E software (v. 3.0.215, Broad Institute ©2013). The unsupervised cluster analysis of all the samples was performed using the column distance/similarity matrix algorithm and the average linkage method with Pearson correlation. Hierarchical clustering of the gene expression between different phenotype clusters was performed using the marker selection algorithm, using a two-sided test with 1000 permutations. The most significantly differential expressed genes were considered those where the false discovery rate (FDR) values were <0.05.
For subsequent analyses at single gene level, non-parametrical comparisons between two groups the two-tailed Mann-Whitney test was used. A two tailed p-value <0.05 was considered statistically significant. Statistical analyses were performed with Graph Pad Prism v 7 for Windows (La Jolla, CA, USA). For ACC patients, the Kaplan-Meier method was used to estimate overall survival (OS, in all patients with primary tumors) and recurrence-free survival (RFS, in patients with complete resection of the primary tumor) while the Cox proportional hazards model was used for univariate and multivariate analyses using IBM SPSS v 26 for Windows (SPSS Inc., Chicago, IL, USA).

Robust Statistical Analysis of Aging Mice

Check if the same lab product or an alternative is used in the 5 most similar protocols
Blinding of investigators was not possible during experiments. Control and experimental groups were randomly assigned by cage. All experiments contained littermates and non-littermates, which were both randomly assigned to control and experimental group. Young control mice were raised or obtained from Jackson Laboratory (WT; C57BL6/J). Statistical significance was calculated by a two-tailed Student’s t-test or ANOVA using a post-hoc test to for multiple comparisons. *P < 0.05; **P < 0.005; ***P < 0.001; ****P < 0.0001. To determine exclusion criteria, GraphPad Prism was used to define statistical outliers, which were then excluded from data analysis. Aged mice with extreme frailty, tumor or other age-related pathology were excluded from the study. This amounted to less than 5% of all aged mice. A confidence interval of 95% was used for all statistical tests. All data were assumed to be normally distributed, unless the standard deviation was identified as significantly different between groups. Sample size for experiments were based upon previously published experiments. All statistical tests were performed using GraphPad Prism v7 for Windows (GraphPad Software). Data are expressed as mean ± s.e.m. Biological replicates and the number of independent experiment repetition are described in the figure legends.

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.
