Differences in observed richness between subgroups. Only significant results are shown. Reported P‐values after Dunn test, with Benjamini–Hochberg corrected P‐values (Kruskal–Wallis test, N = 218, χ ² = 19.24, Pcorr = 0.007).

Comparison	N	Z‐score	Pcorr
BMS‐RRMS_I	218	3.30	0.015
BMS‐RRMS_R	218	2.86	0.021
BMS‐HC	218	3.01	0.019
PPMS‐RRMS_I	218	2.55	0.040
PPMS‐RRMS_R	218	2.40	0.049
PPMS‐HC	218	−2.09	0.092

HC, healthy controls (N = 120, including FGFP samples); PPMS, primary progressive multiple sclerosis (N = 26); BMS, benign multiple sclerosis (N = 20); RRMS_I, interferon‐beta‐treated RRMS (N = 24); RRMS_R, RRMS during a relapse (N = 4); P, uncorrected P‐value; Pcorr, P‐value corrected for multiple comparisons with Benjamini–Hochberg, FDR.
