When did Interatrial Block trials start? (3)

Shown in this order: most recent first, 1990 onwards. 2026 is partial: trials registered with a 2026 start date so far, not a full year.

Trials started per year
Year Trials started
2026 (partial year) 1
2015 1
2013 1

No forecast is made for this condition: it averages 0.2 trial starts a year over the five years to September, under the 5 a year the method needs.

Recruitment duration, a model prediction: none of the 3 trials evaluated at the 2026-10-09 snapshot is predicted and still running. Source: ClinicalTrials.gov / AACT (CTTI), public domain.
