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.

2 · The registry

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

purposeThis study aims to assess effect of sleep disturbance, cancer-related fatigue, and depression on the quality of life (QoL) of breast cancer patients undergoing chemotherapy.

methodA descriptive, cross-sectional study was conducted at an oncology hospital in Cairo, Egypt, from November 2024 to February 2025. A total of 253 breast cancer patients undergoing chemotherapy were recruited through convenience sampling. Data were collected using validated instruments: Pittsburgh Sleep Quality Index (PSQI), Functional Assessment of Cancer Therapy-Breast (FACT-B), Cancer Fatigue Scale (CFS), and Patient Health Questionnaire-9 (PHQ-9) for depression. Linear regression models were employed to analyze the relationships between sleep disturbance, fatigue, depression, and QoL.

resultsFindings revealed that 99.2% of patients experienced fatigue, 87.4% reported poor sleep, and 93.3% exhibited depressive symptoms. Regression analysis demonstrated that sleep disturbance had the strongest negative impact on QoL (B = -1.506, p < 0.001), overshadowing both fatigue and depression. Correlation analysis further supported these findings, with sleep disturbance showing the highest negative correlation with QoL (r = -0.81, p < 0.001), followed by fatigue (r = -0.72, p < 0.001) and depression (r = -0.56, p < 0.001).

conclusionsSleep disturbance, cancer-related fatigue, and depression are significantly associated with reduced QoL in breast cancer patients undergoing chemotherapy. Among these factors, sleep disturbance appears to be the most influential. Interventions targeting sleep quality may help mitigate related psychological and physical challenges, thereby enhancing patients’ overall well-being.
