Title:Cholecystectomy and sphincterotomy in patients with mild acute biliary
pancreatitis in Sweden 1988 - 2003: a nationwide register study
Version: 2Date:11 September 2009
Reviewer: Greger Lindberg
Reviewer's report:
In my modest opinion the manuscript does contain sufficient novel information to
merit publication. I have two minor suggestions.
1. Age should not be given as mean and SD since it is usually not a normally
distributed variable (Table 1). I would prefer median and range or interquartile
range.
2. I wonder if the contribution of age to the case fatality rate could be studied
using a multiple regression model (e.g Cox regression) with age, complications (if
these can be determined from available data), and group as covariates.
