Results: Amongst 100 patients studied, maximum number of patients had grade 2 of acne vulgaris. A positive and significant relationship was observed between Grades of acne and DLQI (Spearman R =0.2326, p=0.01989) at 5% level of significance. Conclusion: A positive and significant relationship was observed between grades of acne and DLQI, meaning higher the grades of acne higher is the effect of DLQI.
