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
backgroundFragmented QRS (fQRS) complex, with various morphology, has been recently described as a diagnostic criterion of several cardiac diseases. However, there are little data regarding the prognostic role of fQRS in peripartum cardiomyopathy (PPCM) patients. We aimed to investigate the effect of fQRS on predicting left ventricular (LV) nonrecovery in patients with peripartum cardiomyopathy (PPCM).
methodsNinety patients (mean age: 34.7 ± 6.5 years) with the diagnosis of PPCM were analyzed retrospectively. The median follow-up period of was 67.0 (12.0-192.0) months. Fragmented QRS was defined as the presence of various RSR' patterns (QRS duration < 120 ms) with or without Q wave, which include an additional R wave (R' prime) or notching of the R wave or S wave, or the presence of more than one R' (fragmentation) without typical bundle branch block. Recovery of LV function was defined as the presence of LV ejection fraction (EF) >45%.
resultsOf the patients, 54 (60%) did not recover LV function at the last follow-up visit (nonrecovery group), while 36 of the patients (40%) exhibited LV recovery (recovery group). LV ejection fraction (EF) and fQRS were identified as independent predictors of LV nonrecovery in patients with PPCM (odds ratio OR: 5.546, 95% confidence interval CI: 0.792-0.979, p = .019 and OR: 5.986, 95% CI: 1.313-11.787, p = .014, respectively).
conclusionOur data firstly indicated that presence of fQRS was a significant predictor of LV nonrecovery in patients with PPCM. The fQRS might assist in identifying high-risk patients.
