Preimplementation and postimplementation median values of HbA1c, anthropometric measurements, diabetes knowledge, attitudes and perceptions, and proportions of self-care practices stratified according to ‘increased HbA1c’ and ‘decreased or unchanged HbA1c’, and p values of comparisons of changes in measured end points among those with ‘increased HbA1c’ against ‘decreased or unchanged HbA1c’

Change in A1CIncreased HbA1c, n=52Decreased/unchanged HbA1c, n=112p Value two independent samples t test of mean change, increased HbA1c vs decreased/unchanged HbA1c
