Meta-analysis of Biomarker Hazard Ratios

Check if the same lab product or an alternative is used in the 5 most similar protocols
Comprehensive meta-analysis (Version 2, Biostat, Englewood NJ) and Stata (Stata/SE 11.2 for Windows; StataCorp LP, College Station, Texas, USA) were used to pool and to meta-analyse results from the individual studies. Pooled results were extracted and analysed as Hazard Ratios (HR) with 95% confidence intervals. Hazard ratios for biomarkers were analysed by subgroup, where possible. Overall Hazard ratios are also presented. A random-effects model was used and 2-sided P values from an inverse variance statistical method are reported.
Statistical heterogeneity was evaluated using the I2 statistic [26 , 27 (link)], which assesses the appropriateness of pooling individual study results and the 95% CI for I2 were calculated using Higgins et al’s method [28 (link), 29 (link)]. Where I2 was >50%, the degree of heterogeneity was considered substantial. Potential publication bias was appraised by visual inspection of the funnel plot of effect size against the SE for each study, with asymmetry formally assessed with Egger’s regression test.

Statistical Analysis of Continuous and Categorical Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
Analyses were performed using STATA/SE 11.2 for Windows; continuous variables were expressed as the mean ± standard deviation or median and range; categorical data were expressed as numbers (percentages). Statistical analyses were performed using the χ2 test and Mann-Whitney test for independent samples, when appropriate. A P value < 0.05 was used as a threshold for statistical significance.

Statistical Analysis of Experimental Data

Check if the same lab product or an alternative is used in the 5 most similar protocols
Statistical analyses were performed using Stata/SE 11.2 for Windows (StataCorp, College Station, TX, USA). Where appropriate, data are presented as the mean ± standard deviation of at least three independent samples. Two sample's mean comparison was performed using Student's t-test. One-way analysis of variance was used to determine differences among at least three groups, and a Bonferroni multiple comparison was performed to test variances within groups. Two-tailed P<0.05 was considered to indicate a statistically significant difference.

Immunohistochemical Analysis of AIM1 in Prostate Cancer

Check if the same lab product or an alternative is used in the 5 most similar protocols
All graphs and statistical analyses for in vitro and in vivo experiments were generated using Prism 6.0 (GraphPad Softward, Inc., La Jolla, CA) using t-test statistics. For analysis of immunohistochemical expression data, since scores were non-normally distributed, non-parametric tests were used to compare their differences depending on the examined tissue. Comparisons were made for membranous and cytoplasmic AIM1 expression. Scores between benign prostate, prostate cancer, and lymph-node metastasis were compared using the Kruskal–Wallis test, adjusting for tied values. Pairwise comparisons were done using the Wilcoxon rank-sum (Mann–Whitney U) test. A two-tailed P < 0.05 was considered statistically significant, except for post hoc comparisons. For the latter, the significance threshold was adjusted using Šidák’s correction, and set to P < 0.017. Data were analyzed using Stata/SE 11.2 for Windows (StataCorp LP, College Station, TX). Gene set enrichment analysis was carried out using the DAVID functional annotation tool69 (link).

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.
