Table 1_Daily intake of cuminaldehyde-rich cumin essential oil improves cognitive function

38 participants aged 65–86 were enrolled in a 12-week randomized, double-blind, placebo-controlled pilot study. The dataset likely contains cognitive performance scores from the Cognitrax test and blood biomarker measurements collected before and after the intervention. Author Kengo Ito published this data under a CC-BY-4.0 license on figshare in April 2026.

Use Cases

• Analyze the effect of cumin essential oil on psychomotor speed based on the reported significant group × time interaction.
• Compare reaction time improvements between intervention and placebo groups based on the results described.
• Explore correlations between cognitive test scores and blood biomarkers mentioned in the exploratory analyses.
• Replicate the statistical analysis of covariance adjusted for age and years of education using the underlying data.

Strengths

• Data originates from a randomized, double-blind, placebo-controlled trial, a rigorous study design.
• Includes results for 38 participants over a 12-week intervention period.
• Cognitive function was assessed using the standardized Cognitrax test.

Limitations

• Row count and column-level documentation are unknown, which may limit suitability assessment.
• The pilot study had a small sample size of 38 participants, limiting generalizability.
• Exploratory biomarker analyses showed no significant group × time interactions, suggesting biological changes were not uniquely attributable to the intervention in this study.
