1 · What the graph read from it

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.

2 · The registry

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

backgroundEclampsia is traditionally considered a complication of hypertensive disorders of pregnancy (HDP). However, atypical cases occur without preceding HDP, and their pathophysiological mechanisms remain unclear. This study aimed to compare the clinical features of eclampsia with and without prior HDP diagnosis.

methodsWe retrospectively analyzed 31 singleton pregnancies with eclampsia diagnosed at nine Japanese perinatal centers between 2007 and 2023. Cases were classified into two groups: eclampsia preceded by HDP (n = 14) and eclampsia not preceded by HDP (n = 17). Clinical characteristics, laboratory findings, and perinatal outcomes were compared.

resultsOf the 31 cases of eclampsia, 17 (57%) were not preceded by HDP, while the remaining cases had been diagnosed with HDP prior to the onset of eclampsia. In the eclampsia not preceded by HDP group, compared to the eclampsia preceded by HDP group, the BMI was significantly lower (22.07 ± 2.05 vs. 25.60 ± 6.19 kg/m

conclusionsAtypical eclampsia without preceding HDP shows distinct clinical features, including later gestational age at onset, higher intrapartum incidence, and elevated inflammatory markers. These findings suggest a need for further investigation into alternative pathophysiological mechanisms and tailored clinical strategies for such cases.
