From: Association between lipid metabolism and periodontitis in obese patients: a cross-sectional study
Correlation analysis of BMI and WHR with periodontal pocket depth and clinical attachment level of the study groups. Partial regression plots of periodontal pocket depth and clinical attachment level with the relative levels of BMI (A) and WHR (B) respectively. All participants from the three groups (normal weight group, overweight group and obesity group) were analyzed for correlation. Correlation analysis results showed that both BMI and WHR were positively correlated with periodontal pocket depth and clinical attachment level (P < 0.05, n = 112, Pearson correlation analysis was used as the statistically test)
