Meta-Analysis of Zingiberaceae Effects on Adult Cognitive Outcomes

A systematic review and meta-analysis published in 2026 synthesizes evidence from 18 randomized controlled trials. The work, authored by Desirée Victoria-Montesinos, evaluates the effects of curcumin, turmeric, ginger, and related preparations on memory and other cognitive domains in adults. The dataset is a 16.6 KB document summarizing the review's methods, results, and discussion.

Use Cases

• Assessing the evidence for memory improvement based on the reported standardized mean difference of 0.57.
• Evaluating domain-specific cognitive effects based on the analysis of memory, executive function, global cognition, and attention outcomes.
• Identifying research gaps for future clinical trials based on the noted heterogeneity and small number of studies.

Strengths

• The analysis is based on 18 randomized, double-blind, placebo-controlled clinical trials.
• Results include a specific standardized mean difference (0.57) with a 95% confidence interval for the primary memory outcome.
• The work has a registered PROSPERO systematic review protocol (CRD420261325966).

Limitations

• The underlying data is a summary document (16.6 KB); raw trial data or detailed results tables are not provided.
• The evidence is described as having substantial heterogeneity, a small number of studies, and risk of bias in some trials.
• Column-level documentation is absent; field semantics must be inferred after download.
