The Association Between Circadian Disruption in Core Body Temperature Rhythm and Post-Chemotherapy Sleep Disturbances in Breast Cancer Survivors.
Article in Journal of sleep research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Sleep disturbance is a common symptom experienced by approximately 70% of breast cancer survivors and persists after the conclusion of chemotherapy. This study aimed to quantify the circadian disruption of the core body temperature (CBT) rhythm and its correlation with sleep disturbance following chemotherapy. In a sample of 25 breast cancer survivors, CBT was measured using an ingestible thermometer pill to calculate the relative amplitude (RA) prior to chemotherapy. The Pittsburgh Sleep Quality Index (PSQI) was employed to assess global sleep quality at three time points: prior to the commencement of chemotherapy, at 1 month (T1) and 9 months (T2) following the conclusion of chemotherapy. Subjective and objective sleep latency (SL
