Results

The LCI and WLI groups comprised 494 and 501 patients, respectively.The mean adenoma number per patient was significantly higher in the LCI group than in the WLI group (1.07 vs. 0.88, p=0.04).
However, the adenoma detection rate was 47.0% in the LCI group and 47.9% in the WLI group, with no significant difference.
