Odds Ratios and their respective p-values in bold exhibit corresponding risk factors as significantly associated with Chronic GORD (ie, GORD with DE).
All study variables expressing p<0.2 in univariate analysis were included in the multivariable analysis and are presented here in this table.
*P<0.05 was considered statistically significant (bold highlight). COR, crude/unadjusted ORs (obtained from univariate analysis); AOR, adjusted ORs for all independent variables (obtained from multivariable analysis, by stepwise selection method).
