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
BACKGROUND AND
aimsThis study evaluated a three-year residential rehabilitation programme, which aimed to support recovery from problem substance use via peer support and social enterprise activities. The aims were to clarify programme mechanisms and identify contextual factors associated with variation in outcomes.
methodsThe study took place within River Garden, a residential rehabilitation for problem substance use, based in South Ayrshire, Scotland. A mixed-methods realist-informed process evaluation was undertaken, using participant observation, repeated qualitative interviews and routinely collected admissions data. Fieldwork was conducted with residents, staff and trustees between April 2019 and November 2020. Nine (of ten) residents were recruited into the study. All residents were male, aged 20-47 years (median 35 years) and were White Scottish or English. Data collection and analysis was guided by Medical Research Council guidance on process evaluation and informed by selected principles from realist evaluation.
resultsThree key contextual factors and six key mechanisms were associated with variation in resident outcomes. The severity of residents' substance use problems, their physical and mental health and their socioeconomic backgrounds shaped whether they responded to the programme's instrumental and relational resources with trust, respect or motivation (constituting six mechanisms, e.g. instrumental-respect, relational-trust). The programme was most beneficial for residents for whom intended outcomes were less constrained by contextual moderators.
conclusionsIn residential rehabilitation for substance use disorders, residents with higher problem severity, worse physical and mental health and greater socioeconomic disadvantage appear to be less likely to respond to rehabilitation resources with trust, respect or motivation compared with the other residents. These findings may support the development of strategies to improve outcomes for residents with greater contextual barriers to change.
