A Novel Scoring System to Improve the Detection Efficiency of Pancreatic Cystic Lesions in the General Population.

The detection rate of PCLs was 0.2% [n/N=3/1,828, Boot strapping bias-corrected and accelerated (BCa) 95% CI 0.1-0.3%] for a total score of 0 points, 0.5% (n/N=12/2,278, BCa 95% CI 0.3-0.8%) for 1.0 point, 1.3% (n/N=5/386, BCa 95% CI 0.8-1.9%) for 1.5 points, 0.8% (n/N=14/1,752, BCa 95% CI 0.5-1.1%) for 2.0 points, 1.6% (n/N=21/1,274, BCa 95% CI 1.1-2.2%) for 2.5 points, 2.1% (n/N=10/476, BCa 95% CI 1.1-3.2%) for 3.0 points, 3.3% (n/N=34/1,020, BCa 95% CI 2.4-4.6%) for 3.5 points, and 5.4% (n/N=19/355, 3.4-7.6%) for ≥4.0 points, showing an increasing trend with the total score of the scoring system (Cochran-Armitage test, p<0.001) ( Table 4 , Fig. 4 ).
