More than 66% of all RCT in JPS reported on eligibility criteria, admission before allocation, random allocation, method of randomization, patients' blindness to treatment, treatment complications, statistical analyses, statistical methods, loss to follow-up, and statistical methods; 2 elements of design and analysis, however, were poorly reported: blind assessment of outcome (33%) and power (17%).
An accounting of missing data values should be provided; if imputed data values are used in statistical analyses, the methods used for imputation should be fully described.
Two BioConductor packages, limma and siggenes, were used to perform the statistical analyses (see methods).
SA provided significant input into the statistical analyses and methods of the paper, interpretation of results, and edited the final version to be published.
Differentially expressed genes that only passed the SAM analysis were colored orange (up-regulated) or light blue (down-regulated); genes that passed both statistical analyses (see Methods) were colored red (up-regulated) or blue (down-regulated).
