Induced Abortion After Previous Caesarean Section: A Scoping Review.
Article in The Australian & New Zealand journal of obstetrics & gynaecology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundPrevious caesarean section (CS) is increasingly common among women undergoing induced abortion.
aimsTo map and analyse existing literature on abortion safety, outcomes and management in those with previous CS. MATERIALS AND
methodsFour databases were systematically searched from inception to July 2024. Primary human studies in English reporting on outcomes, safety or management of first- or second-trimester medical (MToP) or surgical (SToP) abortion in women with previous CS were included. Uterine rupture incidence was analysed cumulatively in the first and secondtrimesters by the number of CS and the type of prostaglandin used. Data on the efficacy and safety of MToP and SToP, including studies reporting on the management of abortion in the setting of abnormal placentation, were collected and analysed by theme.
resultsIn total, 164 articles met inclusion criteria. Incidence of uterine rupture in first-trimester MToP was 0 of 2194 cases, in second-trimester misoprostol MToP in those with 1 previous CS was 0.5% (10/1910) and 2.2% (18/835) in women with ≥ 2 CS (p < 0.001). Mifepristone priming did not increase the rupture rate in second-trimester MToP (p = 0.77). Previous CS was a modest risk factor for retained products after MToP across both trimesters (OR 1.48, CI 1.29-1.70).
conclusionMedical and surgical abortion in the first and second trimester appears safe in women with prior CS; however, risks include uterine rupture, need for surgical intervention and haemorrhage from undiagnosed placenta accreta. Further research and guidance are needed on managing abortion after previous classical CS, ≥ 3 previous CS and those with abnormally invasive placenta.
