Meta-Analysis of Sleep Quality and Cancer-Related Cognitive Impairment, 2,908 Participants

A meta-analysis by Zhenjuan Dang, published in 2026, synthesizes evidence on the link between sleep and cognitive impairment in cancer patients. It aggregates results from 13 studies involving 2,908 participants. The analysis found a moderate negative correlation (r = -0.44) between sleep quality and cancer-related cognitive impairment.

Use Cases

• Validate the association between sleep quality and cognitive impairment based on the reported correlation coefficient (r = -0.44).
• Replicate the meta-analytic methodology using Fisher's z-transformation and standardized regression coefficients as described.
• Inform the design of clinical studies on cancer-related cognitive impairment using the synthesized evidence from 13 studies.

Strengths

• Results are based on a systematic review of 4,037 articles from 8 databases, including Chinese sources.
• Analysis includes 2,908 participants across 13 selected studies, providing a defined sample size.
• Statistical robustness is supported by sensitivity analysis (r = -0.47 to -0.40) and a test for publication bias (p = 0.410).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for direct data analysis.
• The 52.3 KB file size suggests the dataset is a summary document, not a raw data repository.
