Y₁, Y₂, and Y₃ are dichotomous variables (0,1), and having a value of 1 represents HbA1c < 8.0%, blood pressure < 140/90 mmHg, and total cholesterol < 5.5 mmol/L, respectively.
* Adjusted for other variables in the table and for clustering by health centre.
† Males are referent.
‡ Estimated using multivariate probit model. P values below 0.05/8 = 0.0063 (8 because there are 8 independent variables) are declared significant at 5% level.
Odds ratios significant at 0.05 level are shown in bold.
