Single measurement of serum creatinine and urine albumin was used to define CKD; semiquantitative urine albumin was used and so could not grade level of albuminuria, and the assessment of knowledge and attitude was based on self-report with possible risk of bias; we used “yes” or” no” and “agree and disagree” type of questions which limit possible answer of the respondents. The gene discussed is ALB; the disease is chronic kidney disease.
