Correlation between survey-level hemoglobin means and standard deviations in 461 child surveys and 401 women surveys. Correlation of a child (6–59 mo) survey-level Hb SD and Hb means and b non-pregnant WRA (15–49 y) survey-level Hb SD and Hb means using a Hb exclusion range of 4.0–18.0 g/dL. Red circles represent data from surveys conducted in Uganda (n = 56 child surveys and n = 39 WRA surveys). Spearman’s rho was calculated both including and excluding Uganda data.
