Complete case analysis (n = 14839), identifying risk factors for advanced disease at first presentation (CD4 less than 200 cells/mm3 or WHO stage 3 or 4). Model constructed using basic demographic details (Table 1) excepting BMI and education level for which data was missing in a large number of patients. OR: Crude odds ratio, AOR: Adjusted Odds ratio.
