Predictors for back pain in the interventional cardiologists
Multiple logistic regression analyses identified that female gender [relative to male: odds ratio (OR) 2.353, 95% CI 1.485 to 3.777, p<0.001], the type of ICPs (relative to conducting arrhythmia catheter ablation: OR for PCI 2.088, 95% CI 1.106 to 3.995, p=0.024; OR for conducting two or more ICP 1.779, 95% CI 1.008 to 3.177, p=0.048), personal annual volume of ICPs (relative to 100 cases or less: OR for 101 to 300 cases 1.659, 95% CI 1.059 to 2.614, p=0.028; OR for 301 to 500 cases 2.182, 95%CI 1.296 to 3.705, p=0.004; OR for > 500 cases 3.302, 95%CI 1.816 to 6.112, p<0.001) were associated with the occurrence of back pain. The results of the multiple logistic regression analyses are illustrated in Figure 2.
