Intravesical Bacillus Calmette-Guerin treatment-induced sleep quality deterioration in patients with non-muscle invasive bladder cancer: functional outcome assessment based on a questionnaire survey and actigraphy.
Article in Supportive care in cancer : official journal of the Multinational Association of Supportive Care in Cancer, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 2 of them syntheses that pooled 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.
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
purposeWe investigated sleep parameters and patient-reported outcomes before, during, and after induction Bacillus Calmette-Guerin therapy using questionnaires and actigraphy in patients with non-muscle invasive bladder cancer.
methodsWe investigated 10 patients who received Bacillus Calmette-Guerin therapy once weekly for 8 weeks. The International Prostate Symptom Score, European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30, Functional Assessment of Cancer Therapy-Bladder, and multi-item Short Form-8 tools were used to assess patient-reported outcomes. Participants completed all questionnaires before (baseline), at the 4th and 8th doses, and 1 month after the last Bacillus Calmette-Guerin dose. The MotionWatch8 was fastened to patients' waist throughout the study. Composite sleep quality was determined based on sleep duration, efficiency, and fragmentation.
resultsWe observed a transient increase in frequency/nocturia subscores and the insomnia subscore. The number of patients with poor sleep quality increased from 0 (0%) at baseline to 7 (70%) at the 4th dose and to 6 (60%) patients at the 8th dose. Among 10 patients, 6 (60%) were assigned to the sleep deterioration group and 4 (40%) to the non-deterioration group. Sleep quality was restored to baseline levels in 5 of 6 patients (83%) within 1 month after the last dose in the sleep deterioration group, and the nocturia subscore of the International Prostate Symptom Score was significantly increased only in this group (P=0.03).
conclusionsThis is the first study that confirms intravesical Bacillus Calmette-Guerin-induced sleep quality deterioration based on a questionnaire survey and actigraphy.
