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.

Abstract

introductionPatient trust in healthcare providers (PTP) is critical for improving treatment adherence and outcomes in substance use disorders. As concurrent opioid and methamphetamine use increasingly complicates methadone maintenance treatment (MMT), understanding PTP in this population is essential. This study aimed to examine factors associated with PTP among people on MMT using methamphetamine in Vietnam.

methodsWe analyzed baseline data from a randomized clinical trial (NCT04706624) evaluating adaptive, evidence-based interventions to reduce methamphetamine use among MMT patients in Vietnam. The analysis included 412 MMT patients using methamphetamine who completed the 10-item Trust in Physicians Scale. Guided by the Social Ecological Framework, we examined individual, interpersonal, health-system, and socio-cultural factors associated with PTP using linear mixed-effects regression models.

resultsThe mean PTP score was 36.6 out of 50. Female patients (

conclusionFindings underscore the need to reduce provider stigma, ensure consistent care quality across clinics, and strengthen rapport with female and educated patients. Leveraging social support and the stability of long-established clinics may foster greater PTP.
