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
purposePatient hesitancy to use MC due to the fear of negative social implications leads to intentional non-adherence and compromises therapeutic outcomes. Hence, we aimed to determine the rate of patient adherence to MC and explore factors influencing patient MC use.
methodsDemographic and quantitative data related to MC usage were extracted from medical records for patients prescribed MC at a single cancer centre in metropolitan Sydney. Qualitative data was generated from semi-structured interviews. Interview guides were developed based on the Theory of Planned Behaviour (TBP) domains (i.e. Attitudes, Subjective Norms, Behavioural Intention and Perceived Behavioural Control) to elucidate themes influencing MC use. A mixed method approach involving triangulation of quantitative and qualitative methods was used for data analysis.
resultsTwenty patients were included in the study, and the majority of patients showed adherence (n = 14, 70%). The MC formulation used (p = .018), symptom relief (p = .001) and side effects experienced (p = .007) significantly influenced MC adherence. In addition to side effects experienced, findings for barriers to adherence were convergent or complementary for other medication-related factors, including the inconvenience of MC co-administration with food, cost and unpleasant taste.
conclusionsMC adherence is influenced by its effectiveness for symptom relief whereby appropriate MC formulation selection is crucial and should be determined by the indication (or symptom clusters). Social factors such as the views and experiences of close others had little bearing on MC adherence.
