P-values obtained from the examination of the relationship between PROG and FTD clinical subgroups were corrected for multiple testing using the False Discovery Rate method (Benjamini and Hochberg, 1995).
Differences in the distribution of experimental markers between subgroups were investigated with Kruskal-Wallis equality-of-populations rank test corrected for ties, follo-wed by pairwise Mann–Whitney tests, which are reported uncorrected for multiple testing.
To correct for multiplicity of comparisons in subgroup analyses, P-values of paired comparisons between subgroups were adjusted by Bonferroni-Holm procedure [ 36].
No differences between subgroups were identified.
No large differences between subgroups were observed.
Furthermore, variations between subgroups were observed.
Comparisons between subgroups were made using this method.
Comparisons between subgroups were made using unpaired t tests.
Differences between subgroups were tested with the χ test.
Differences between subgroups were tested using random-effects meta-regression.
