Hormonal and electrolyte predictors for methotrexate versus surgery in ectopic pregnancy.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
This retrospective study investigates the association between maternal serum electrolyte and hormone levels and the success of methotrexate (MTX) treatment in ectopic pregnancies, aiming to identify predictive factors and improve clinical outcomes. A total of 372 patients treated with single-dose MTX between 2012 and 2023 were included, divided into two groups: those who successfully responded to MTX and those requiring surgical intervention. Significant differences were observed in beta-hCG levels, with a mean of 1376 in the MTX-successful group and 2358 in the surgical group. Electrolyte analysis showed that patients who responded successfully to MTX had higher potassium and albumin levels, whereas magnesium levels were lower compared to the surgical group. Haematological parameters also varied, with higher hemoglobin and hematocrit levels observed in the MTX-successful group. The findings suggest that serum potassium, magnesium, and albumin levels may be predictive markers for MTX efficacy. Higher potassium and albumin levels, along with lower magnesium levels, may contribute to improved treatment outcomes. These results support the potential role of dietary interventions-such as increasing potassium and albumin intake and moderating magnesium levels-in enhancing MTX success rates. This study underscores the importance of maternal biochemical profiles in guiding treatment strategies for ectopic pregnancy and highlights the value of individualized approaches to optimize outcomes and minimize the need for surgical intervention. Future research should aim to elucidate the biological mechanisms underlying these associations and validate the findings in larger and more diverse patient populations.
