Table 2 Univariate and multivariate logistic regression models evaluating the associations of dipyridamole-thallium scan with the rates of 90-day cardiac complications, 90-day mortality, and 1-year mortality

From: Does preoperative dipyridamole-thallium scanning reduce 90-day cardiac complications and 1-year mortality in patients with femoral neck fractures undergoing hemiarthroplasty?
