Trial Outcomes & Findings for Alternate Day Versus Daily Oral Iron Therapy in Adolescents (NCT NCT05007899)

NCT ID: NCT05007899

Last Updated: 2023-09-13

Results Overview

Percentage of eligible patients who consent to be enrolled in the study. A secure screening and enrollment log will be kept. Each screened patient will be categorized as either: ineligible, eligible but not approached, eligible and enrolled, eligible and declined. If the latter (eligible and declined), the reason for declining will also be obtained and noted in the study log.

SECONDARY outcome

Timeframe: 12 week study visit

Pill counts were performed as an objective measure of adherence. Subjects were given a specific number of pills for the duration of the study. At the 12 week visit they were asked to return any remaining pills, which were then counted and compared to the number of expected pills should be remaining, assuming 100% adherence. These numbers were used to calculate an estimate of adherence.
