Sample technique: Cluster Sampling.
Sample size:                                                         

N = Z2 p x q

P = prevalence of adherence to therapy given by WHO.,P=50% Allowable Error of 7.5%,Final sample size= 376 rounded off to 400 (after adding 10% sample loss).
Selection criteria: Diagnosed Hypertensive subjects who were on treatment for more than 1year.
