β-Coefficient (95% CI) P
MUAC 0.003 (−0.002, 0.009) 0.20
MUACZ 0.003 (−0.002, 0.008) 0.20

WLZ 0.130 (0.129, 0.131) <0.001

Impact of percent dehydration on measurement indices; model assessed for linearity, additivity, independence, homoscedasticity, and normality; controlled for both age and sex. MUAC, midupper arm circumference; MUAC, midupper arm circumference z score; WAZ, weight-for-age z score; WLZ, weight-for-length z score.
