    Figure: Kaplan-Meier Time-to-Event Estimate Plots

    A, Global recurrence based on family history, smoking, and disease location. Recurrence events were significantly negatively associated with cessation of smoking (P < .05) and with distal ileum-colon localization of the disease (P < .01). B, Surgical recurrence in side-to-side isoperistaltic strictureplasty (SSIS) based on family history of inflammatory bowel disease and disease location. Surgical recurrence in SSIS alone was associated with significant reduction in patients without a family history and with a disease localization in the distal part of the bowel.

    Figure: Imaging of Pulmonary Nodule Suspicious for Cancer

    A, Computed tomographic scan of a 68-year-old smoker identified a pulmonary nodule suspicious for cancer. The patient was injected with a near-infrared dye systemically prior to surgery. B, During surgery, the surgeon could visualize the tumor. C, Near-infared imaging better defined the borders of the tumor and did not reveal any evidence of metastatic disease. Arrowhead marks tumor in all 3 images.

    Figure 1: Trends in Risk Factors in Veterans Administration Patients Who Underwent Coronary Artery Bypass Grafting (CABG) Surgery From 1997 to 2011

    Simple linear regression analysis was used. A, Age. B, Body mass index (BMI) (calculated as weight in kilograms divided by height in meters squared). C, Diabetes mellitus. D, Advanced congestive heart failure (CHF) (New York Heart Association class III or IV heart failure). E, Left main coronary artery disease. F, Independent functional performance status. G, Advanced angina class (Canadian Cardiovascular Society class III or IV). H, Prior myocardial infarction [MI]. I, Ejection fraction of 34% or less. J, Current smoker. K, Urgent surgery. L, Emergent surgery. P < .05 was considered significant for the trends.

    A, Postoperative arterial events depending on different combinations of smoking and history of cardiovascular disease (CVD), defined as any of the following: hypertension (requiring medication), angina (in 30 days prior), dyspnea (at rest, on moderate exertion, or none), congestive heart failure (in 30 days prior), myocardial infarction (in 6 months prior), previous percutaneous coronary intervention, previous cardiac surgery, peripheral vascular disease (requiring revascularization, angioplasty, or amputation), rest pain, transient ischemic attack, or cerebrovascular accident without or with neurologic deficit. No CVD in the never smoker group constituted the reference group. B, Postoperative respiratory events according to different combinations of smoking and history of chronic obstructive pulmonary disease (COPD). No COPD in the never smoker group constituted the reference group.
