MicroRNA‐155 (miR-155) as an accurate biomarker of periodontal status and coronary heart disease severity: a case–control study

Table 3 Pearson correlation test coefficients (r) calculated between whole blood miR-155 expression and study participant age, BMI, gender, clinical parameters and salivary IL-1β protein levels, for control (C), generalized periodontitis (P), CHD and clinically healthy periodontium (AS-C); and CHD with generalized periodontitis (AS-P) groups
