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
objectiveWe aimed to probe the clinical value of N-terminus pro-brain natriuretic peptide (NT-proBNP), myeloperoxidase (MPO), and neutrophil lymphocyte ratio (NLR) combined with echocardiography in the prediction of malignant arrhythmias (MA) in elderly patients with valvular heart disease (VHD).
methodsMPO, NT-proBNP, and NLR were detected in blood samples. After 1 year of follow-up, receiver operating characteristic curves were analyzed to determine the clinical value of NT-proBNP, MPO, NLR, and echocardiography for predicting MA in patients with VHD.
resultsMPO, NT-proBNP, and NLR were higher in the VHD group. MPO, NT-proBNP, and NLR were higher with severe cardiac dysfunction. MPO, NT-proBNP, NLR, and LVESV in the MA group were higher. NT-proBNP was an independent factor influencing the occurrence of MA in elderly patients with VHD. The AUC for predicting MA in elderly patients with VHD using NT-proBNP, MPO, NLR, and echocardiography were 0.782 (sensitivity 61.50%, specificity 94.60%, 95% CI 0.630-0.934), 0.759 (sensitivity 69.20%, specificity 81.10%, 95% CI 0.579-0.938), 0.736 (sensitivity 76.90%, specificity 64.90%, 95% CI 0.562-0.910), and 0.782 (sensitivity 76.90%, specificity 75.70%, 95% CI 0.646-0.918), respectively. The AUC for the combined prediction using NT-proBNP, MPO, NLR, and echocardiography was 0.913 (sensitivity 76.90%, specificity 94.60%, 95% CI 0.820-1.000), higher than that of each parameter alone (P < 0.05).
conclusionThe combination of NT-proBNP, MPO, NLR, and echocardiography has a predictive value in detecting MA in elderly VHD patients.
