Table 3.

Multivariable odds ratios for IM with 95% CIs (adjusted for age and sex) derived from East London GP database. P values represent empirical p values for each level of the predictor (3rd column) and likelihood ratio p values (4th column) represent the additional improvement in model fit on adding the predictor to a null model consisting of only age and sex
