APOE and Alzheimer disease: CTRP14 showed marked correlations with MMSE score (rs = −0.170, p = 0.047) and CDR‐SB score (rs = 0.215, p = 0.012) (Figure 1L,M), with male AD patients taking negative correlations of CTRP14 with MMSE score (rs = −0.392, p = 0.004) and MoCA score (rs = −0.280, p = 0.047) (Figure 1N,O), while APOE4‐positive AD patients having a positive correlation of CTRP14 with ADL score (rs = 0.273, p = 0.038) (Figure 1P).
