Meta-Analysis of Sleep Quality and Cognitive Impairment in 2,908 Cancer Patients

13 articles with data from 2,908 participants were analyzed to evaluate the association between sleep quality and cancer-related cognitive impairment. The analysis, conducted by Zhenjuan Dang and published on figshare in March 2026, found a moderate negative correlation (r = -0.44). The work is a systematic review registered under PROSPERO RD420251090655.

Use Cases

• Validate the correlation between sleep disturbances and cognitive decline based on the reported pooled correlation coefficient.
• Inform the design of clinical interventions targeting sleep to mitigate cognitive impairment.
• Serve as a benchmark for future meta-analyses on cancer-related cognitive impairment.
• Support systematic reviews on non-pharmacological management of chemotherapy side effects.

Strengths

• Analysis is based on 13 studies aggregating data from 2,908 participants.
• Results include a specific pooled correlation coefficient (r = -0.44) with a 95% confidence interval.
• Sensitivity analysis confirmed result robustness across a range (r = -0.47 to -0.40).
• Publication bias was assessed and not detected (p = 0.410).

Limitations

• The dataset is very small at 43.6 KB, indicating limited raw data scope.
• Column-level documentation is absent; field semantics must be inferred after download.
• The underlying participant data from the 13 source studies is not directly accessible.
