35 protocols using spss statistics 26.0 for windows

1

Statistical Analysis of Continuous Variables

Continuous variables are expressed as the mean ± standard deviation. Statistical analyses were performed using the software package SPSS Statistics 26.0 for Windows (SPSS Inc., Chicago, IL, USA). Bland–Altman plots were drawn using MedCalc 15.2.2 (MedCalc Software bvba, Ostend, Belgium). Statistical significance was set at P < 0.05.

Biometric Measurements in Surgical Patients

Check if the same lab product or an alternative is used in the 5 most similar protocols
Continuous variables are expressed as the mean ± standard deviation. Statistical analyses were performed using independent samples t-test and paired samples t-test with SPSS Statistics 26.0 for Windows (SPSS Inc., Chicago, IL, USA). Univariate linear regression was performed to show correlations between patient characteristics and changes in measurements. Bland–Altman plots were performed using MedCalc Statistical Software (version 15.0; MedCalc Software, Inc., Mariakerke, Belgium) to assess the agreement of biometric measurements between preoperative and postoperative data. Statistical significance was set at P < 0.05.

Evaluating Visual Acuity Changes

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analyses were performed using the software package SPSS Statistics 26.0 for Windows (SPSS Inc, Chicago, IL, USA). The Kolmogorov‒Smirnov test was used to assess data normality. Continuous variables of normality are expressed as the mean ± standard deviation (SD) or the median. Comparisons between preoperative and postoperative visual acuity were performed using paired t-tests. Statistical significance was set at P < 0.05.

Factors Influencing Social Participation

Check if the same lab product or an alternative is used in the 5 most similar protocols
The relationship between participants’ characteristics and their degree of social participation was analyzed using t-tests or chi-square tests. To identify the factors relevant to social participation, binomial logistic regression analysis (forced entry method) was conducted with social participation as the objective variable. Since mobility and the need for care were highly related, the need for care was not entered into the logistic regression analysis. SPSS Statistics 26.0 for Windows was used for all statistical analyses, with a significance level set at < 5%.

Evaluating AI Grading in Ophthalmology

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analysis of the data was performed using the SPSS Statistics 26.0 for Windows (SPSS Inc., Chicago, IL, USA). The consistency between two ophthalmologists was evaluated using the Kappa coefficient, and the sensitivity and specificity of AI automatic grading were calculated regarding the results from ophthalmologists as the gold standard. The number of referrals confirmed by AI and the ophthalmologists was calculated and compared.

Analyzing Sociodemographic Factors in Research Surveys

Check if the same lab product or an alternative is used in the 5 most similar protocols
Data analysis was performed using SPSS Statistics 26.0 for Windows by showing descriptive statistics, including frequencies and percentages. Response percentage was calculated by the score of positive responses as agree/strongly agree and negative responses as disagree/strongly disagree. Negatively worded questions marked with R, which are Reversed Scores, were considered by calculating the percentage of positive responses as disagree/strongly disagree and the percentage of negative responses from agree to strongly agree. Mean, median, and SD were calculated for each item.
Analysis of variance test was performed to check the differences between sociodemographic characteristics for the positive mean response by each domain. The significance level was set at P < 0.05, and Tukey post-hoc analysis was performed for the difference between groups.

Cytotoxic Effects of Chalcone Derivatives

Check if the same lab product or an alternative is used in the 5 most similar protocols
IBM SPSS Statistics 26.0 for Windows was used. The results were displayed as mean ± SEM. To obtain meaningful results, media ± 2SD was used to perform the statistical evaluation of the effect of chalcone derivatives against the metabolic viability of tumor cell lines. The normality of the distribution of the results was confirmed by the Shapiro–Wilk test of normality, and the homogeneity of variance assumption was checked using Levene’s test. One-way Anova was conducted for the experimental cytotoxicity analysis with Bonferroni’s correction post hoc test. The differences in cytokine mRNA expression were analyzed using the Student’s t-test. Statistical significance was considered for p < 0.05.

Respiratory Responses to Cycling Conditions

Check if the same lab product or an alternative is used in the 5 most similar protocols
Data are presented as mean ± standard deviation (SD). All statistical analyses were performed using SPSS statistics 26.0 for Windows (IBM Inc). All breathing variables were analyzed using a two‐way analysis of variance (ANOVA) for repeated measures with condition (LC and WC) and stage (rest, stage 1, stage 2, and stage 3). Similarly, the spirometry and respiratory muscle pressure data recorded at pre‐ and postexercise were also analyzed using two‐way ANOVA for repeated measures, including time (before and after cycling) and condition (LC and WC). When a significant interaction was found, post hoc multiple pairwise comparisons were performed with the Bonferroni correction. p values of <0.05 were considered statistical significance.

Assessing Physical Activity Assessment Methods

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analysis was conducted with IBM SPSS Statistics 26.0 for Windows (International Business Machines, Armonk, NY, USA). Extreme values of more than three times the interquartile distance were identified using boxplots and excluded from further analysis. Normal distribution was examined with the Kolmogorov Smirnov test after the exclusion of extreme values. Analyses of variance with repeated measurements (ANOVAs) or Friedman-tests were performed to assess differences in PA with light and moderate to vigorous intensity between the three methods. If no sphericity was given, the Greenhouse–Geisser correction was used. Significant differences were examined with the Bonferroni post hoc test. As sedentariness was not assessed with the GPAQ 50+, differences in the assessment of sedentariness between the MW8 and the MM+ were examined while performing a t-test for paired samples or the Wilcoxon-Test. An alpha <0.05 was considered to be 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.
