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: Following identification of barriers to living-donor kidney transplantation, and subsequent development of a multicomponent intervention, we undertook a feasibility trial of the intervention. Trial design: Two-arm, parallel group, pragmatic, individually-randomised, controlled, feasibility trial, comparing the new intervention with usual care, with a mixed-methods parallel process evaluation. Based at two UK hospitals. Participants: Individuals were eligible if ≥18 years old, active on the kidney transplant waiting list or had been referred for transplant listing without a contraindication to transplantation. Individuals with a living-donor undergoing surgical assessment were excluded. Intervention: i) A meeting between a home educator for a dedicated discussion about living-donor kidney transplantation, living kidney donation and potential donors;ii) A standardized letter from a healthcare professional to a candidate's potential donors;iii) A home-based education and family engagement session undertaken by a living kidney donor and a nurse specialist. Objective: To establish the acceptability and feasibility i) of delivering the developed intervention in existing care pathways, and ii) of undertaking a randomised controlled trial of the intervention. Primary outcomes: Recruitment and retention. Randomisation: Participants were randomly allocated 1:1 to i) the intervention or ii) usual care, stratified by site. Minimisation was used to ensure balance in sex, age group, and socioeconomic strata, with probability weighting of 0.8. Results: 183 people were invited to participate. 62 people (34% recruitment) were randomised. 62/62 (100%) completed nurse assessed follow-up at 6 weeks. 51/62 (82%) completed follow-up questionnaires. 3/30 (10%) in the usual care arm and 9/32 (28%) in the intervention arm had individuals ask to be tested for living kidney donation following recruitment to the trial. Conclusions: Intervention and trial delivery are feasible and acceptable. Findings have informed the design of an effectiveness and cost-effectiveness trial.
