Table 2 Chi-square tests were performed for dichotomous factors of cement leakage and univariate logistic regression analyses were performed for continuous factors of cement leakage

From: Risk factors for cement leakage and nomogram for predicting the intradiscal cement leakage after the vertebra augmented surgery
