Gastrostomy tube (G-tube) placement is a long-term alternative to oral or nasogastric feeding for premature infants who cannot safely feed orally or need supplemental nutrition for growth. We compared daily weight changes for G-tube infants 14 and 30 days preplacement and postplacement, excluding the first 7 days post-G-tube insertion. We also estimated a treatment effect model in which infants with a G-tube were matched 1:1 to untreated controls based on propensity scores; main outcome was the average treatment effect (weight gain) for treated infants during the 7, 14, or 30 days immediately prior to discharge.
