Fig 2 Forrest plot of Cox proportional hazards model in clinical N2 including comparison of postoperative chemotherapy alone to preoperative chemotherapy alone. ∗Variables with fewer than 10 patients were included in the Cox but not represented in the graph because of wide confidence intervals. (BAC = bronchioloalveolar carcinoma; Chemo = chemotherapy; CI = confidence interval; HR = hazard ratio; Postop = postoperative; Preop = preoperative.)
