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: Peripheral artery disease (PAD) is a chronic atherosclerotic condition, affecting 20% of adults over 60 in the UK. Guideline-recommended therapy (pharmacotherapy and lifestyle change) has been shown to reduce major cardiovascular and limb events and increase life expectancy; however, adherence is low. Currently, there is a paucity of patient-centred interventions that address all aspects of adherence. Our previous research highlighted that patients' perceptions of their disease and its treatment strongly influence adherence. However, the views of relatives and healthcare professionals (HCPs) have not been previously explored. Purpose: To explore the views, experiences, perceived barriers and facilitators to adherence to guideline recommended therapy from the perspectives of patients with PAD, their relatives and HCPs. Methods: Semi-structured qualitative interviews were conducted with patients with PAD, their relatives and HCPs. Participants were purposively sampled to capture a wide range of perspectives. The Perceptions and Practicalities Approach framed the topic guide and guided analysis. Interviews were recorded, transcribed verbatim, and analysed thematically (inductively and deductively). Stakeholder groups of patients, public and clinicians supported the pilot testing of the topic guide and the data analysis. Results: Fifteen patients (eight men and seven women, aged 48-82, 8/15 White British), four relatives (all women) and 18 HCPs (five from primary and 13 from secondary care) were interviewed. Seven themes were identified: (1) Knowledge & understanding, (2) Treatment concerns, (3) Motivation, (4) HCP influence, (5) Social & physical context, (6) Everyday reality, (7) Healthcare system factors. Patients, relatives and HCPs did not always align on perceptions. Conclusion: Our findings illustrate that patients' adherence to PAD treatment is a complex process shaped by their personal understanding, motivation and daily lives, as well as support from HCPs and the wider system. To enhance adherence, future interventions should focus on improving patient education, addressing misconceptions about the necessity of conservative treatment, fostering individual motivation through practical goal setting, and strengthening collaborative care across the healthcare system.
