N is the total number of individuals in the adjusted analysis
^aGlucose levels expressed as medians as non-normally distributed. Diff. could not be calculated here
^bNo adjustment
^cAdjusted for age, sex, high WHR (>0.90 for males and 0.85 for females) and rainy season
^dImpaired Glucose Tolerance
^eImpaired Fasting Glucose
^fDiabetes Mellitus
^gThe test person has any of IGT, IFG or DM, or a combination
