In Reply: In response to Drs Keim and Teich, we suggest that publication or rejection of trials in top medical journals may be more related to quality than publication bias against negative studies.1 A number of published studies (21 to our knowledge) have reported alterations in established disease genes from various subgroups of patients with pancreatitis. Unfortunately, few investigators have applied the stringent criteria for idiopathic pancreatitis used in our study, and none have investigated the extended families of patients with seemingly sporadic trypsinogen mutations. Because this was the specific focus of our study, and because of the limit for references in our Research Letter, we restricted citations to the most relevant work for our report.
