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
Objective: Poor medication adherence is common among breast cancer patients undergoing endocrine therapy. Although previous studies have shown that symptom distress, illness perception, and fear of recurrence can have a connection with medication adherence, the underlying mechanism remains unclear. This study explored the effect of symptom distress on medication adherence, the mediating role of illness perception between symptom distress and medication adherence, and the moderating role of fear of recurrence among those factors. Methods: Symptom distress, illness perception, fear of recurrence, and medication adherence were assessed in 405 patients. A structural equation model verified the mediating role of illness perception, and a multi-cluster analysis tested the moderating role of fear of recurrence. Results: Illness perception had a mediating effect between symptom distress and medication adherence (effect size: -0.213), accounting for 28% of the total effect. A significant difference was observed in the path coefficient of "illness perception → medication adherence" between the low and high fear of recurrence group (CR = |-3.578| > 1.96, Conclusions: The links of symptom distress and medication adherence were mediated by illness perception, whereas fear of recurrence moderated this relationship. To improve medication adherence, oncology nurses should alleviate symptom distress and implement interventions for patients with high fear of recurrence to reduce negative illness perception.
