Notes: †Results are presented for the group of iTrack patients who had successful suture tensioning (n=74) since the authors stratified the results for these patients by iTrack alone and CE+iTrack. NR: not reported. Lewis et al did not report medication data for group of patients with successful suture tensioning. However, for the entire iTrack study cohort (n=94 patients), medication use declined from 1.9±1.0 at baseline to 0.6±0.9 at 12 months. See reference¹¹ for the iTrack study and reference¹⁷ for the iStent study.
