IL6 and myalgic encephalomeyelitis/chronic fatigue syndrome: In Table 3, in the non-intervention group, the BDI-II score, mMRC grade, CFS, TFI, SGRQ and K-BILD scores, peripheral IL-6 and TNF-α levels were significantly higher after follow-up than at baseline (P = 0.012, P = 0.001, P < 0.001, P < 0.001, P = 0.002, P < 0.001, P = 0.007, P < 0.001), while the FVC %pred, DLCO %pred and 6MWT levels were significantly lower after follow-up than at baseline (P < 0.001, P < 0.001, P = 0.008).
