Reported research conditions
Counts describe indexed registry records, not efficacy or total research activity. A trial can count under several conditions or countries. Unknown dates are excluded from the start-year chart; future years reflect planned starts. Stopped studies may reflect recruitment, funding or strategy and are not automatically treatment failures.
