Effect of Perioperative Statin Therapy on Postoperative Graft Occlusion, Overall and According to Prespecified Subgroups Following IPW Adjustment. Shown are odds ratios for the incidence of graft occlusion after off-pump CABG (assessed by MSCTA) among patients with perioperative continuation of statin therapy (CS group) as compared with those with discontinuation of statin therapy (DS group). For each prespecified subgroup, after IPW propensity-score adjustment, squares represent odds ratios and horizontal lines represent 95% confidence intervals, with values and results of the P for interaction significance test presented alongside. A square to the left of the vertical line indicates a benefit associated with perioperative continuous statin use, but the benefit is significant at the 5% level only if the horizontal line does not overlap the vertical line.
