Critical Appraisal
Published research can offer valuable insights, but a paper’s conclusions may go beyond what its results support. Critical appraisal examines the methods, findings and limitations to clarify what can reasonably be concluded—and what remains uncertain.

Insights
Cinnamon supplementation has favorable effects on diastolic blood pressure and long-term effects on systolic blood pressure.
Out of 927 records, 8 trials that enrolled 582 participants were included. The pooled effect size showed that systolic blood pressure did not change following cinnamon supplementation. Also cinnamon supplementation in long-duration (≥ 8weeks) had a significant effect on systolic blood pressure. Pooled analysis showed that cinnamon had a significant effect on diastolic blood pressure. In addition, results from both duration subsets and high dose (>1500 mg/day) of cinnamon supplementation were significant.
