  1. The data is presented as mean ± SD (except for TSH level which showed non-normal distribution and is expressed as median) for continuous variables and as percentage (number) for categorical variables. P value was calculated at 95 % confidence interval among CKD stages 3–5 for different variables using one way ANOVA and Kruskal Wallis test for continuous variables, and chi square test for categorical variables
