Weight growth velocity curves from term-equivalent age to 6 years, stratified by gestational age (GA) group and sex. The x-axis shows postmenstrual age in weeks (40 weeks postmenstrual age corresponds to term-equivalent age), and the y-axis shows weight growth velocity (kg/year). a, b, and c show boys born at GA 22–24, 25–27, and 28–31 weeks, respectively; d, e, and f show girls in the same GA groups. Solid lines (boys) and dashed lines (girls) represent the model-estimated mean weight growth velocity, and shaded areas indicate the 95% confidence intervals.
