Baseline mother’s milk DHA levels. Comparison of baseline milk DHA levels between women who reported taking DHA supplements (0.23%, IQR 0.17, 0.34; n = 43) and those who did not (0.15%, IQR 0.11, 0.19; n = 41) during lactation. Group medians compared with Mann-Whitney statistical test. Symbols (dots) represent individual participant data, bar represents median, lines represent IQR. Worldwide average breast milk DHA level from Brenna et al [10] is indicated by the dashed line
