Note: Data were analyzed using MANCOVA test adjusted for age, income and number of co-morbidities. ^aMultiple comparisons using Bonferroni test. *The mean difference is significant at p<0.025 level. PCS = Physical Component Summary, MCS= Mental Component Summary, M_diff = Mean difference and SE= Standard Error, CI= Confidence Interval.
