Values are estimated marginal means ± SEs [number of studies included in the analyses] (number of people included). The estimated marginal means were calculated from linear mixed-effects models using the lmer and emmeans functions in R (R Foundation for Statistical Computing). Hb, hemoglobin; SF, serum ferritin; TSAT, transferrin saturation.
