highly significantP < 0.0001
The PADIT risk score was found to be highly significant ( P < 0.0001), with an estimated hazard ratio (HR) and corresponding 95% confidence interval (CI) of 1.28 (95% CI 1.22, 1.33) ( Table 3 ); thus, the relative risk of a major CIED infection increased by 28% for each one unit increase in PADIT risk score.
