Analysis of the ability of acylcarnitine levels to predict CD4⁺ T cell count. a–e Survival analysis of levels of MC, PC, OC, SC, or the combination of MC, PC, SC, and OC. Subjects were divided into high-level and low-level groups, according to the cutoff points with the largest sum of sensitivity plus specificity in ROC curves. CD4⁺ T cell count of > 700 cells/μL were considered the end point. Kaplan–Meier survival curves and the log-rank test were used to assess predictive ability
