1 · What the graph read from it

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.

2 · The registry

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

The Salford Lung Study in Asthma (SLS Asthma) was a multicentre, randomised, controlled, open-label trial that assessed initiating once-daily, single-inhaler fluticasone furoate/vilanterol (FF/VI) 100 μg/25 μg or 200 μg/25 μg versus continuing usual care. A subgroup (n = 400) from SLS Asthma was enrolled in this exploratory, interview-based follow-up study. Quantitative and qualitative data were collected via questionnaires. The primary objective was to capture patient-centred outcomes (symptom experience, quality of life [QoL], disease management behaviours) and patient experience. Secondary objectives were to assess the correlation of patient-reported outcomes with pre-defined variables from SLS Asthma (Asthma Control Test [ACT] score). The follow-up sample was representative of the SLS Asthma population; half reported asthma improvement during the study. Breathlessness was the most likely symptom to improve (47.8% of patients reported improvement). Most patients reported 'no change' in overall QoL (57.5%) and daily life domains (functioning 66.3%, activities 68.3%, relationships 86.8%, psychological 68.5%). Functioning was reported as the most frequently improved domain (29.8% of patients). Perceived improvement in asthma control (42.5%) and confidence (37.3%) was frequent. ACT responders (defined as patients achieving an ACT score ≥20 and/or an increase of ≥3 in ACT score from baseline at Week 52) were more likely to report asthma improvement (88.7% of patients reporting 'a lot' of improvement) than non-responders. Patients' asthma experiences generally improved during SLS Asthma. Clinical improvements were often associated with perceived improvement by patients, particularly among ACT responders.
