wheezeNo significant differenceaOR: 0.85, 95% CI: 0.63-1.16
maternal intake in the highest vitamin E quartile versus lowest reduced the odds of wheeze at 2 years by 36% (aOR: 0.64, 95% CI: 0.47-0.87, n = 2 observational studies, very low certainty); this was not true for vitamin C intake (aOR: 0.85, 95% CI: 0.63-1.16, n = 2 observational studies, very low certainty)
