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
objectivePatients with gastrointestinal tract cancer reported suboptimal adherence to oral anticancer agents (OAAs), reducing the therapeutic benefit. According to the Common-Sense Model of Self-Regulation, patients' medication perceptions decide adherence. However, how perceptions of OAAs influence adherence remains unknown among this population. This study explored this relationship.
methodsA convergent mixed methods study was conducted. In the quantitative part, medication perceptions were evaluated among 253 participants using the Beliefs about Medicines Questionnaire, Perceived Sensitivity to Medicine, and Self-efficacy for Appropriate Medication Use Scale. Adherence was measured by the Morisky 4-item Medication Adherence Scale. In the qualitative part, 37 participants from the quantitative cohort were interviewed concurrently. Perceptions of OAAs were identified using content analysis. Findings were integrated using side-by-side comparisons and joint displays.
resultsQuantitative data showed that 58.89% of patients were considered adherent. Adherent patients exhibited lower harm beliefs, less sensitivity to medicine, and higher medication self-efficacy. Qualitative data identified four categories of perceptions: emphasizing the effectiveness of OAAs despite the hazardous nature, experiencing negative emotions in relation to taking OAAs, taking responsibility for OAAs routine management, and encountering multiple barriers to taking OAAs. The qualitative findings supplemented the quantitative results regarding the associations between harm beliefs, perceived sensitivity to medicine, medication self-efficacy, and adherence; however, they revealed a discordance in the associations between necessity beliefs, concern beliefs, and adherence.
conclusionsStrategies targeting medication perceptions were suggested to promote adherence to OAAs, particularly those aimed at modifying negative medication beliefs and emotions, enhancing medication self-efficacy, and improving self-management abilities.
