Table 2.

Sample medians of SIFS pattern amplitude, interval, frequency, and displacement rate as functions of group (CTR, ALS, PSP) and pattern (STC, BAF, UBF, PBF); patterns STC and BAF taken together represent the aggregate of all SIFS patterns; patterns UBF and PBF are subsets of BAF

Rows with bold italic print show the sample medians of the aggregate of all patterns; these values are virtually identical to the sample medians of individual SIFSs. Regular print shows medians for each combination of group and pattern. Symbols a, b and c in columns ALS and PSP indicate two-sided corrected p < 10^–2, < 10^–3, and < 10^–4, respectively, with regard to the adjacent left column (i.e. group differences ALS–CTR and PSP–ALS), those in column CTR apply to the differences PSP–CTR (only calculated for data pooled across patterns); α, β and γ, corresponding p values with respect to adjacent upper row (pattern differences)
