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
purposeAdherence to oral chemotherapy remains a significant challenge in cancer care, potentially compromising treatment efficacy and patient outcomes. Emerging evidence suggests that patients' perceptions of their illness may influence adherence behaviors. This study aimed to evaluate patients' perceptions of their illness and examine their association with adherence to oral chemotherapy.
methodsThe descriptive and cross-sectional design study was conducted with 90 patients who received oral chemotherapy in the oncology polyclinic of a university hospital. "Personal Information Form," "Illness Perception Scale," and "Oral Chemotherapy Adherence Scale" were used to collect data. Descriptive statistics were used to summarize participant characteristics. Based on the distribution of variables (assessed via Kolmogorov-Smirnov/Shapiro-Wilk tests), appropriate parametric and non-parametric tests were used. Spearman's rank-order correlation evaluated associations between illness perception components and adherence.
resultsThe most common symptom experienced by the patients in the identity dimension was fatigue (88.9%). In the illness representation, the average score of the subscale of illness coherence (9.43 ± 2.25) was the lowest. Oral Chemotherapy Scale total score was 78.41 ± 6.57. Weak but statistically significant positive correlations were found between adherence and personal control (r = 0.293), treatment control (r = 0.294), and illness coherence (r = 0.259) (p < 0.05).
conclusionWhile causality cannot be inferred due to the cross-sectional design, findings suggest that stronger perceived control and a better understanding of illness are associated with higher adherence to oral chemotherapy. These results highlight the importance of integrating psychosocial assessment and tailored education into supportive cancer care practices.
