PRO endpoints were identified in more trials (2.3 increase\/year, 95% CI: 1.6\u20132.9) from an increasing variety of countries (0.7\/year) (95% CI: 0.4\u20130.9) over time. PROs were typically secondary endpoints (207, 89.6%). 15\/77 (19.5%) completed trials reported results on the ClinicalTrials.gov results database, and of those eight included their PRO results. Eighteen trials had published manuscripts available on ClinicalTrials.gov. Three (16.7%) used PROs to confirm the maximum tolerated dose.
