Myocardial injury within 24 hours of Viperidae snake envenomation: a prospective cohort study-a single-center experience from Chongqing, China.

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
Myocardial injury following Viperidae snake envenomation significantly worsens clinical outcomes and healthcare burden, yet its early diagnostic predictors remain understudied. In this prospective cohort study from Chongqing, China, we analyzed 75 Viperidae-envenomed patients and 78 healthy controls within 24 h post-bite, assessing electrocardiographic abnormalities, cardiac biomarkers (high-sensitivity cardiac troponin I, creatine kinase), inflammatory markers (C-reactive protein), and echocardiographic right ventricular strain parameters. Results demonstrated a 14.7% incidence of myocardial injury, with 24.0% of patients exhibiting ECG abnormalities, alongside significant elevations in cardiac biomarkers and inflammatory markers (P < 0.05). The absolute values of Right Ventricular Free-wall Strain (RVFWS) and Global Longitudinal Strain (RVGLS) were significantly reduced in envenomed patients, especially in those with concomitant myocardial injury (P < 0.001). Both parameters demonstrated high diagnostic performance: RVFWS-area under the ROC curve 0.846 (95% CI 0.742-0.950); RVGLS-area under the ROC curve 0.825 (95% CI 0.700-0.950). Delayed hospitalization (> 1 h post-bite) independently predicted myocardial injury risk (OR = 1.178, P < 0.05), highlighting the critical need for rapid intervention. These findings identify RVFWS and RVGLS as sensitive early diagnostic markers for cardiac complications and underscore the importance of timely hospitalization to mitigate myocardial injury.
