Identifying sleep disturbance- and fatigue-related factors of poor health-related quality of life in patients with advanced ovarian cancer.
Article in Journal of patient-reported outcomes, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundGiven that sleep disturbance and fatigue are pervasive among patients with advanced ovarian cancer (OC) and associated with poor health-related quality of life (HRQoL), several patient-reported outcome measures have been used to assess symptom burden. However, it remains unclear which patient-reported topic domains are most important to HRQoL for advanced OC patients. This study aimed to assess the domains of sleep disturbance and fatigue associated with poor HRQoL among patients with advanced OC across their treatment trajectory. METHODOLOGY: We conducted an online survey with adults diagnosed with Stage III or IV OC in the last three years. Patients reported clinical and sociodemographic characteristics, sleep disturbance and fatigue levels using Patient-Reported Outcomes Measurement Information System (PROMIS) short forms, and HRQoL using the CDC Healthy Days measure. Hierarchical regression models were used to assess how sleep disturbance and fatigue short-form items predicted poor HRQoL, specifically the number of days where poor health interfered with daily life and poor physical and mental health days (unhealthy days) in the past month, compared to clinical (time since treatment, treatments received, metastatic status) and sociodemographic (age, gender, marital status, employment) factors.
resultsAmong the 200 participants diagnosed with advanced OC (71.50% Stage III, 28.50% Stage IV; 33.50% receiving chemotherapy, 44.00% receiving maintenance therapy), sleep disturbance and fatigue were significantly associated with poor HRQoL. Compared to clinical and sociodemographic variables, sleep disturbance levels explained 17.00% more variance in the number of unhealthy days in the past month; fatigue levels explained 30.00% more variance in the number of unhealthy days. Among short form items, having difficulty falling asleep (β = 0.17, p = .03), fatigue interfering with physical function (β = 0.24, p < .01), and feeling run-down (β = 0.35, p < .01) were the strongest predictors of poor HRQoL.
conclusionPatients with advanced OC reported significantly elevated levels of sleep disturbance and fatigue, which were associated with poor physical and mental health. Findings highlight the importance of screening for difficulty falling asleep, interference with physical function, and feeling run-down to connect patients with supportive care that may improve their HRQoL during and after treatment.
