Association between previous spontaneous abortion and preeclampsia: a case-control study.
Article in BMC pregnancy and childbirth, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 10 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
backgroundThe association between previous spontaneous abortion and preeclampsia is not yet fully understood. The current study was conducted to assess the association between previous spontaneous abortion and preeclampsia among pregnant women in Sudan.
methodsA case-control study (involving 180 women in each study group) was conducted at Saad Abuelela Hospital, Khartoum, Sudan. The cases were pregnant women with preeclampsia, while the control group included healthy pregnant women. The participants' sociodemographic, obstetric, and clinical characteristics were assessed via a questionnaire.
resultsThere was no significant difference in the age, parity, education level, employment status, blood group, body mass index, and hemoglobin level between the patient and control groups. Forty (22.2%) women with preeclampsia and 68 (37.8%) women in the control group had a history of spontaneous abortion (p = 0.001). Multivariate logistic regression analysis (adjusted) revealed that women with a history of spontaneous abortion had a lower risk of preeclampsia than those without a history of spontaneous abortion [adjusted odds ratio (AOR) = 0.44, 95% confidence interval (CI) = 0.26‒0.73]. However, women with a history of preeclampsia had a higher risk of recurrence of preeclampsia (AOR = 1.92, 95% CI = 1.11‒3.32).
conclusionThe present study revealed that previous spontaneous abortion reduced the risk of preeclampsia by 59.0%.
