A Randomised, Controlled Trial of a Low-energy Diet for Improving Functional Status in Heart Failure With PRESERVED Ejection Fraction Preserved Ejection Fraction

Model scores of the 29,894 trials active now.

Model score 19% for any early termination, 6% for termination due to slow enrollment. Past trials like this one (phase, sponsor type and disease area, started 2008–2016) ended terminated 15% of the time (107 trials).

Finished trial that started in 2015 or later: the model never saw it during training.

Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2026-06-17. The rest of the way to 100% is still running.

From the competing-risks survival model (termination vs completion, still-running trials censored), fit to trials that started 2008–2014 and recalibrated to termination rates over 2022–2024, since termination has become more common. Checked on past years, it still ran a little low when the rise continued.
