Correlation of periodontal inflamed surface area with glycemic status in controlled and uncontrolled type 2 diabetes mellitus

Figure 2 Correlation between clinical attachment loss and glycated HbA1c in well-controlled type 2 diabetes mellitus group, uncontrolled type 2 diabetes mellitus group without microvascular complications and uncontrolled type 2 diabetes mellitus group with microvascular complications. A significant positive correlation existed between the mean clinical attachment loss and HbA1c (Pearson correlation coefficient: 0.451, P < 0.001). CAL: Clinical attachment loss; HbA1c: Hemoglobin A1c.
