§All observations recorded between 31th–189th day from start date were grouped in period 1, 190th–378th day in period 2, 379th–566th day in period 3, 567th–755th day in period 4, 756th–943th day in period 5 and 944th to till end of the study period in period 6.

¶Difference in mean change; a negative change indicates a fall in average from baseline to end line.

BMI, body mass index; DBP, diastolic blood pressure; SBP, systolic blood pressure.
