Acute Left Heart Failure in Twin Pregnancies: Clinical Characteristics and Outcomes-A 10‑Year Retrospective Analysis of 24 Cases.
Article in Journal of clinical hypertension (Greenwich, Conn.), 2026. 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 evaluated the clinical characteristics, management, and maternal-neonatal outcomes of 24 twin pregnancies complicated by acute left heart failure (ALHF) delivered at Peking University Third Hospital from January 2015 to December 2025. Patients were stratified by timing of onset (antenatal vs. postnatal). The mean maternal age was 33.8 years, and 70.8% had preeclampsia. ALHF occurred antenatally in 9 cases (37.5%) and postnatally in 15 cases (62.5%). Dyspnea was the most common initial symptom (79.2%). The mean left ventricular end‑diastolic diameter was 50.6 ± 3.7 mm, and the median NT‑proBNP level was 1406.0 pg/ml (IQR: 1146.5-2053.5 pg/ml). All patients received multidisciplinary care and diuretics, with 37.5% requiring intensive care. Full cardiac recovery by 6 weeks postpartum was achieved in 87.5% of patients. The preterm birth rate was 87.5%, and the perinatal mortality rate was 10.4%. Compared with the postnatal‑onset group, the antenatal‑onset group had significantly higher NT‑proBNP levels at disease onset or diagnosis (2388.5 vs. 1257.0 pg/ml, p = 0.018), longer hospital stay (11 vs. 8 days, p = 0.019), earlier gestational age at delivery (30 vs. 36 weeks, p = 0.002), and higher rates of neonatal intensive care unit admission (92.3% vs. 40.0%, p = 0.01) and perinatal mortality (27.8% vs. 0, p = 0.016). In conclusion, ALHF in twin pregnancies predominantly occurs postnatally and is frequently associated with preeclampsia; maternal outcomes are favorable with multidisciplinary care, whereas neonatal outcomes were poorer in the antenatal-onset group, likely reflecting medically indicated early preterm delivery in the setting of maternal decompensation.
