Relationship between sleep-related impairment and cognitive functioning among breast cancer survivors.
Article in Journal of cancer survivorship : research and practice, 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
purposeSleep-related impairment and cancer-related cognitive decline (CRCD) are common, disruptive symptoms affecting breast cancer survivors. This study examined the association between sleep-related impairment and both self-reported and objective cognitive functioning in breast cancer survivors following treatment.
methodsParticipants (N = 253) from the I Can! Improving Cognition After Cancer study completed the NIH Toolbox Digit Symbol test to measure Processing Speed and a battery of neurocognitive tests of Memory, Executive Functioning, and Attention domains. Self-reported cognition was assessed with the PROMIS Cognitive Function and Abilities scales. Sleep-related impairment was measured by the PROMIS Sleep-Related Impairment scale. Multiple linear regression models were used to examine the associations between sleep-related impairment and the six cognitive outcomes, adjusting for demographic and cancer treatment factors.
resultsParticipants were on average 59 (SD = 8.9) years old, majority identified as White (77%) and were college graduates (42%). Fifty-seven percent of participants underwent chemotherapy, 80% received hormone therapy, and 81% were treated with radiation. Greater sleep-related impairment was significantly associated with worse executive function (β = -0.01, 95% CI: -0.022, -0.000, p = 0.04), worse cognitive abilities (β = -0.28, 95% CI: -0.375, -0.184, p < 0.001), and worse cognitive function (β = -0.25, 95% CI: -0.323, -0.167, p < 0.001). No significant associations were observed for memory, attention, or processing Speed.
conclusionGreater sleep-related impairment was associated with poorer self-reported cognitive functioning and modest differences in executive functioning among breast cancer survivors, underscoring the importance of addressing sleep-related impairment in this population. IMPLICATIONS FOR CANCER SURVIVORS: Assessing sleep-related impairment during survivorship care may help identify survivors experiencing cognitive difficulties and related daytime functional concerns.
