An RR or HR of 1 represents no effect; an AUC of 0.5 represents chance and an AUC of 1.0 represents a perfect test. Thus, the best-performing anthropometric index would have the lowest RR or HR and the highest AUC. “RR” indicates an RR per 1-unit z score or 1 cm of MUAC; “HR” indicates the HR per 1-unit z score or 1 cm of MUAC. LAZ, length-for-age z score; MUAC, midupper arm circumference; WAZ, weight-for-age z score; WLZ, weight-for-length z score.
2
Adjusted for age, sex, HIV, and small size at birth (see Supplemental Table 2).

Values are RRs (95% CIs) for “Inpatient mortality” and HRs (95% CIs) for “Postdischarge mortality.”
