How to read this
Confirmed events carry a source that states the date: a PDUFA goal date in a sponsor release, an advisory committee notice, a congress programme. Expected events are our estimate from the registry primary completion date and sponsor statements; treat them as a quarter, not a day.
Companies are attached directly for catalysts and derived for readout-calendar rows from the products named (each product’s companies in the corpus). Past events stay in the data and can be shown with the checkbox.
