• Corrected Abstract or Commentary: Platelet count/spleen diameter ratio predicted the presence of esophageal varices in liver cirrhosis



Thanks to Dr. Daniel J. Brotman of the Cleveland Clinic Foundation for pointing out an error in the confidence interval for sensitivity in “Platelet count/spleen diameter ratio predicted the presence of esophageal varices in liver cirrhosis” (1). The correct values appear in the Table.


Table. Operating characteristics of platelet count/spleen diameter ratio (cutpoint ≤ 909 for a positive diagnosis) for predicting the presence of esophageal varices in liver cirrhosis*

Patient groups Sensitivity (95% CI) Specificity (CI) +LR −LR
Derivation set 100% (96 to 100) 93% (82 to 98) 14.3 0.0
Validation set 100% (95 to 100) 42% (28 to 57) 1.7 0.0
Compensated cirrhosis 100% (98 to 100) 71% (60 to 81) 3.5 0.0
