SGA and LBW
Six47,48,60-63 and
five37,46,59,61,62 studies reported SGA and LBW as
outcomes, respectively. When results were pooled, women in the top
tertile of diet quality scores had a lower risk of SGA (OR: 0.88; 95 CI:
0.79, 0.99; I2 = 5%; P-heterogeneity = 0.39; Figure
S2) and LBW (OR: 0.60; 95 CI: 0.37, 0.99; I2 = 23%;
P-heterogeneity = 0.27; Figure S3) compared to those in the bottom
tertile. All studies were of high quality (NOS score ≥7) (Table S2).
