Slopes of the relationship between initial W/L and subsequent length gain during each 3‐month interval (cm/3 months per 1 unit Z‐score in W/L), by study, controlling for infant sex, maternal height and initial L /A. Slopes with different superscripts are significantly different between studies (P < 0.05). The main effect of initial W/L was significant (P < 0.001) at all age intervals. The interaction between study and initial W/L was significant at 1– 4 months (P = 0.04), 5–8 months (P = 0.0007) and 6–9 months (P = 0.0034), but not at 2–5, 3–6, 4–7, 7–10, 8–11 or 9–12 months. At 1– 4 months, initial W/L was significantly associated with subsequent length gain in Ghana (P < 0.0001), but not in the U.S. or Honduras‐LBW studies. At 5–8 months, initial W/L was significantly associated with subsequent length gain in all sites (P ≤ 0.001) except Ghana (P = 0.08). At 6–9 months, the relationship was significant in the two Honduras studies (P < 0.001), but not in Ghana or the U.S. (though no pairs of slopes differed significantly from each other).
