Prognostic significance of hyponatremia in peripartum cardiomyopathy.
Article in World journal of methodology, 2025. 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
backgroundHyponatremia is the most common electrolyte imbalance, however the prognostic significance of hyponatremia in peripartum cardiomyopathy (PPCM) remains unclear.
aimTo assess the prognostic significance of hyponatremia in PPCM patients.
methodsWe consecutively recruited patients with PPCM from 14 sites in Nigeria and followed them up for a median of 18 months. Serum sodium was measured at baseline, and patients with hyponatremia (< 135 mmol/L) were compared with those with normal sodium levels. Cox proportional hazards regression models were developed to identify factors associated with all-cause mortality.
resultsOf the 191 PPCM patients recruited, 90 (47.1%) had hyponatremia at presentation. All-cause mortality among the hyponatremic patients (24/90; 26.7%) was significantly higher than among patients with normal serum sodium (7/101; 6.9%) (
conclusionHyponatremia was common in our cohort of PPCM patients, and was independently associated with a threefold increased risk for all-cause mortality. Hypotension and a LVEF below 25% at presentation were also independent predictors of mortality.
