The authors observed significant differences in the mean SARC-F scores regarding economic level (p = 0.004), smoking (p = 0.001), disease status (p < 0.001), opportunistic infections (p = 0.001), CD4 T-cell count (p < 0.001), sarcopenia construct, and its components HGS and GS, all at a significance level of 0.001 (Table 1). Here, CD4 is linked to sarcopenia.
