Fragmented QRS in patients with preeclampsia.
Article in Archives of gynecology and obstetrics, 2024. 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
purposeThis study aims to investigate the prevalence, clinical correlates, and prognostic implications of fragmented QRS complexes (fQRS) in pregnant women with preeclampsia (PE), shedding light on the potential role of electrocardiographic markers in identifying cardiac involvement in hypertensive disorders of pregnancy.
methodsPatients with PE and age-matched low-risk control patients were recruited at a tertiary hospital between January 2015 and January 2023. A comprehensive assessment, including heart rate, PR duration, QRS duration, corrected QT duration, and fragmented QRS, was conducted by 12-lead electrocardiography. Baseline clinical characteristics, laboratory parameters, and electrocardiographic findings were compared between the study groups.
result128 preeclampsia patients and 122 age- and comorbidity-matched controls were included in the study. The prevalence of fQRS was significantly higher in preeclamptic women compared to normotensive controls (14.1% vs. 3.3%, p = 0.04). ALT levels of pregnant women with preeclampsia and without preeclampsia groups were 43,77 (35.25-48.22) and 23,18 (13.75-33.00) (p: 0.038), respectively. In univariate regression analyses, Na and fragmented QRS were found to be associated with preeclampsia. (p: 0.016 and 0.009, respectively). After multivariable adjustment for variables, Na and fragmented QRS remained strongly associated with preeclampsia (OR: 4.787 (1.556-14.720), p: 0.06; 0.941 (0.893-0.992), p: 0.023, respectively).
conclusionThis study provides compelling evidence of an association between preeclampsia and fragmented QRS complexes, implicating electrolyte imbalances and hemodynamic stress as potential contributors to myocardial electrical instability in hypertensive disorders of pregnancy. Further research is warranted to validate these findings and improve risk stratification and clinical outcomes in affected women. Number: 2023/4705 Retrospectively Registered.
