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.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Introduction Prescribing of inhaled therapy, pressurised metered-dose inhaler (pMDI) technique at hospitalisation, and therapy concordance pre-admission remains inadequate. A study by Asthma UK (2010-2013) found over 125,000 asthma prescribing errors and that one-third of patients had ineffectual inhaler technique. Aims and objectives This study aims to identify the adequacy of inhaled therapy prescriptions and assess pMDI technique and pre-admission inhaler concordance among patients with airways disease using the pMDI technique checklist and the Test of Adherence (TAI) questionnaire. Methods A two-centre prospective study was performed over three months in 2022 at two secondary-care hospitals in the UK. Data were obtained from prescriptions, including availability of inhalers at 24 and 72 hours and the number of devices. A pMDI technique checklist and assessment of concordance using the TAI questionnaire were performed by trained practitioners. Results Seventy patients were recruited (median age = 73; chronic obstructive pulmonary disease (COPD): n=50, asthma: n=20). Inhaled therapy was prescribed correctly in 80% (n=56); 54% (n=38) and 70% (n=49) had their inhalers supplied within 24 and 72 hours of hospital admission, respectively. Sixty-nine percent (n=48) used two or more different devices on admission. Fifty-seven percent (n=39) had ≥1 critical error with pMDI inhaler use. Seventy-one percent (n=48) of patients were graded as "good adherence" on the TAI questionnaire. Conclusions Inhaled therapy was well prescribed, but availability of inhaled devices within 48 hours of admission could be improved. Assessment of pMDI inhaler technique during hospitalisation is recommended. Initiation of combination inhalers for patients using two or more different devices may improve concordance. The TAI was used in an acute setting for the first time, but a larger study is needed to evaluate its full potential during hospitalisation.
