Where they differ
From the rowsThe best-graded row, grade C, is a meta-analysis of 145 people (2021) and found an improvement.
The 2 rows that found an improvement were larger: a median of 118 people, against 50 people for the row that found no difference.
Only the 2 rows that found an improvement include pooled reviews of several trials (1 of 2); the row that found no difference is a single study.

Both fennel and placebo groups improved; there was no difference between groups on any menopausal symptom except one urinary item. The authors attribute the null result to a high placebo response.
