Evaluating single-dose methotrexate alone versus methotrexate with letrozole for treating ectopic pregnancy: a comparative study.
Trial report in Archives of gynecology and obstetrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeEctopic pregnancy (EP) constitutes 1-2% of all pregnancies. Methotrexate (MTX) is commonly used in treating EP, but it has some limitations and potential side effects. Clinical studies have shown that letrozole, an aromatase inhibitor, may potentially be used in conjunction with MTX therapy. In our study, we explored the efficacy of adding letrozole to MTX in managing EP.
methodsBetween June 2021 and September 2022, a total of 60 patients diagnosed with EP at the Faculty of Medicine, Yüzüncü Yıl University, were randomly divided into two groups. Group 1 received MTX alone, while Group 2 received a combination of MTX and letrozole. The primary outcome measure was the change in serum β-hCG levels. Secondary outcomes included the need for surgical intervention and the occurrence of side effects.
resultsBoth groups demonstrated similar success rates in treatment, and there was no significant difference between the MTX and MTX + letrozole groups regarding the need for surgical intervention. Although β-hCG levels declined more rapidly in the MTX + letrozole group, these decreases were not statistically significant. The combination of MTX and letrozole in the treatment of ectopic pregnancy has shown similar efficacy to single-dose MTX.
conclusionLetrozole may offer a potential contribution to MTX therapy by providing a more pronounced reduction in β-hCG levels, but further research with larger sample sizes and longer follow-up periods is needed to confirm these findings.
