Additional file 1 of Log odds of positive lymph nodes as a novel prognostic predictor for colorectal cancer: a systematic review and meta-analysis

Additional file 1: Figure S1. Egger���s funnel plots on OS and DFS. a-b Egger���s Funnel plot analysis of studies on OS ((a) LODDS1 vs. LODDS0, (b) LODDS2 vs. LODDS0). c-d Egger���s funnel plot analysis of studies on DFS ((c) LODDS1 vs. LODDS0, (d) LODDS2 vs. LODDS0). HR, hazard ratio; OS, overall survival; DFS, disease-free survival; LODDS, log odds of positive lymph nodes; SE, standard error; SND, standard normal deviate.
