The table shows the generic inverse variance weighted pooled mean differences or pooled risk ratios with their corresponding 95% CIs comparing MMS and IFA intervention groups. Number of infants were calculated from effective sample sizes.
Abbreviations: CI, confidence interval; IFA, iron and folic acid supplementation; MMS, multiple micronutrient supplementation; MUAC, mid-upper arm circumference; MUACZ, mid-upper arm circumference z-score; N.A., non applicable.
