Electronic health record data analysis on the impact of rescue-triggered inhaled corticosteroids on controller therapy in Black and Latinx individuals from a pragmatic, open-label, patient-level randomised trial.
Trial report in BMJ open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02995733 (Patient Empowered Strategy to Reduce Asthma Morbidity in Highly Impacted Populations), which is not on this map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

Abstract
objectiveThe Person Empowered Asthma Relief (PREPARE) study found that as-needed inhaled corticosteroid (ICS) supplementation combined with participants' usual controller and rescue therapy reduced asthma exacerbations for Black and Hispanic/Latinx individuals. We aimed to determine whether treatment assignment to the intervention group (Patient Activated Reliever-Triggered ICS (PARTICS)) versus the control group (usual care) influenced controller therapy based on clinicians' written prescriptions.

interventionsEffects of adding ICS to rescue therapy among black and Hispanic adults with moderate-to-severe asthma. OUTCOME MEASURES: For PARTICS therapy impact on patients, each month is the 28-month period (12 months prior to enrolment, the month of enrolment and 15 months after enrolment), a patient was assigned to a controller step based on a six-step classification scheme. A linear mixed effect spline model was completed for before and after enrolment data to determine controller changes over a 28-month period between the two study arms.
resultsThis analysis included 713 participants. Of these, 49.1% were usual care patients and 50.9% were PARTICS patients. Throughout the study, the majority of patients changed asthma controller medications in both arms. By the end of the study, the usual care patients were at a significantly higher asthma controller medication step (0.20 step higher) than the PARTICS patients.
conclusionsClinicians' prescribing patterns showed significant changes over time. Compared with usual care patients, PARTICS patients were on lower doses of asthma controller medications by the end of the study. TRIAL REGISTRATION NUMBER: NCT02995733.
