Indian patients are not a subgroup

Field notes

The project uses a shared data dictionary, defined follow-up schedule, and common registry platform so separate Indian centres can record comparable digestive-disease cases over time. Its rationale is grounded in marked geographic and clinical differences: the page lists gallbladder cancer incidence of 8.9 per 100,000 in Delhi versus 0.8 in Chennai, and cites a 32-centre pancreatitis series covering 1,086 patients. The page says the first study is open, while the registry interface itself sits on a separate subdomain.
