Abbreviations: APS, animal protein score; DPS, dietary protein score; DQDPS, diet quality based on dietary protein score; IE, intrinsic eczema; PPS, plant protein score; QDGIS, quality of diet based on glycaemic index score; SMCGES, Singapore/Malaysia Cross-sectional Genetic Epidemiology Study.
A chi-square P-value < 0.001 (as adjusted by Bonferroni’s correction for multiple comparisons) is considered statistically significant.
