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

backgroundPeripartum cardiomyopathy (PPCM) is a rare disease that causes heart failure during pregnancy or in the early postpartum period, and there were no reports on the trend of clinical condition and treatment in Japan. This explanatory retrospective study aimed to investigate the changes in clinical conditions and treatment in patients with PPCM.

methodsTwenty-three patients (aged 22-43 years; mean age, 32 years) with PPCM from four hospitals in Nagasaki Prefecture were included. We compared the heart failure status and treatments of PPCM between the 10 years from January 2002 to December 2011 (first era) (N = 10) and the 11 years from January 2012 to December 2022 (second era) (N = 13).

resultsLeft ventricular ejection fraction (LVEF) on admission was higher (first era 20% (interquartile range (IQR) 17-34) vs. second era 34% (IQR 25-37), p = 0.0213), and less patients treated with inotropes in patients in second era than those in first era (first era 6/10 (60%) vs. second era 2/13 (15%), p = 0.0393). Hospitalization period was shorter in second era than those in first era (first era 38 days (IQR 22-45) vs. second era 19 days (IQR 16-22), p = 0.0159).

conclusionIn recent years, patients with PPCM have been admitted before progression of LV dysfunction, and that may be related to a decrease in use of inotropes and hospitalization period in Japan.
