[The study design and one year data have been reported previously - see NELM abstract below.]   The following findings were noted:   . The proportion of patients with one or more systemic serious adverse events was significantly higher with bevacizumab than ranibizumab (234 [39.9%] vs. 190 [31.7%]; adjusted risk ratio, 1.30; 95% CI, 1.07?1.57; P = 0.004).   . Gastrointestinal disorders (e.g., haemorrhage, hernia, nausea, and vomiting), were significantly higher in bevacizumab treated patients (11 (1.8%) ranibizumab-treated vs 28 (4.8%) bevacizumab-treated patients; P = 0.005).   . Venous thrombotic events occurred in 3 (0.5%) ranibizumab-treated patients and in ...
