Efficacy and safety of as-needed albuterol-budesonide versus albuterol in patients with asthma aged 12 to <18 years: design of the randomised, double-blind, parallel-group phase IIIb ACADIA trial.
Article in BMJ open respiratory research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06307665 (A Randomized, Double-blind, Multicenter, Parallel-group, Phase IIIb 52 Week Study Evaluating the Efficacy and Safety of PT027 Compared With PT007 Administered as Needed in Participants 12 to < 18 Years of Age With Asthma), which is not on this map.

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
introductionAsthma among adolescents (aged 12-<18 years) is a common condition with high disease burden. Many are undertreated, at risk of adverse outcomes and exhibit poor adherence to maintenance medication. As-needed albuterol-budesonide 180/160 µg reduced the risk of severe exacerbations by 27% compared with as-needed albuterol 180 µg in patients aged ≥12 years, with moderate-to-severe asthma receiving inhaled corticosteroid (ICS) maintenance therapy in the MANDALA trial. A small number of adolescents were included in MANDALA, but data were inconclusive. The randomised, double-blind, multicentre, phase IIIb ACADIA trial is evaluating as-needed albuterol-budesonide versus as-needed albuterol in adolescents with asthma. METHODS AND ANALYSIS: A planned 440 adolescents (aged 12-<18 years) with asthma using as-needed albuterol with low- to high-dose ICS-containing maintenance medications (with or without other controllers) and who had ≥1 severe exacerbation in the previous 12 months are randomised to as-needed albuterol-budesonide 180/160 µg or as-needed albuterol 180 µg for 52 weeks while continuing their own maintenance therapy. The primary endpoint is the annualised rate of severe asthma exacerbations. Secondary endpoints are the time to first severe asthma exacerbation and annualised total systemic corticosteroid exposure for asthma per participant. To minimise the number of adolescents exposed to study medications, the treatment effect will be estimated by partially extrapolating results from the patient population in the MANDALA trial using a Bayesian dynamic borrowing approach. ETHICS AND DISSEMINATION: Ethical approval was obtained from the investigators' institutional review boards. Enrolment began in May 2024. Results will be presented at respiratory congresses and published in peer-reviewed journals. TRIAL REGISTRATION NUMBER: NCT06307665.
