Figure 3From: Sublobectomy versus Lobectomy for stage IA (T1a) non-small-cell lung cancer: a meta-analysis studyForest plot of HR for OS impact of operative approach (sublobectomy versus lobectomy) of stage IA NSCLC patients with data after 2000. The combined HR displayed in this figure suggested there was no statistical significance between sublobectomy and lobectomy on OS (HR 1.38; 95% CI, 0.95 to 2.00; P = 0.09). CI, confidence interval; df, degree of freedom; HR, hazard ratio; OS, overall survival [16–18].Back to article page
