Outcomes of peripartum cardiomyopathy in North Africa: insights from a single-center observational study in Tunisia.
Observational study in BMC pregnancy and childbirth, 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
backgroundPeripartum cardiomyopathy (PPCM) is a rare but potentially life-threatening condition. Due to the scarcity of epidemiological data in North Africa, we conducted this study to assess the outcomes of PPCM in our region. MATERIALS AND
methodsThis monocentric retrospective cohort study involving all patients diagnosed with PPCM was conducted between January 2010 and December 2022.
resultsTwenty-seven PPCM patients, with a median age of 33 years (Interquartile range (IQR) = 9), were included. 52% of patients were diagnosed during the postpartum period. Dyspnea New York Heart Association III/IV(NYHA III/IV) was the most common functional symptom (85%). The median left ventricle ejection fraction (LVEF) was 30% (IQR = 11%). Atrial fibrillation occurred in 11.1% of patients, thromboembolic complications occurred in 18.5%, Pulmonary edema occurred in 85% of patients and cardiogenic shock occurred in 14.8% of patients, with two patients requiring Extracorporeal Membrane Oxygenation (ECMO) support. The predominant mode of delivery was a cesarean Sect. (82% of patients), and the indication for a cesarean delivery was obstetrical in 59% of patients. Prematurity occurred in 36% of newborns, and intrauterine fetal death occurred in one pregnancy. The median follow-up was 24 months [6-144 months]. LVEF recovery was noted in 67% of patients. Bromocriptine was administered to six patients (22%), and none of these patients died and out of them, five patients recovered their LVEF (83%). The overall mortality rate during the follow-up period was 15%, comprising three in-hospital cardiac deaths and one occurring two years later due to refractory advanced heart failure. No significant differences were observed between LVEF recovery and LVEF non-recovery groups. Factors significantly associated with mortality were multiparity, poor antenatal care (ANC) attendance, thromboembolic events, cardiogenic shock, and Pulmonary edema. Five patients with LV recovery subsequently became pregnant, none experienced a relapse of PPCM. However, one of the descendants of a patient was diagnosed with dilated cardiomyopathy.
conclusionThis study revealed that the diagnosis of PPCM in our hospital is often delayed until symptoms become more advanced, resulting in high morbi-mortality.
