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
Acute carbon monoxide poisoning-induced myocardial injury is easily overlooked. However, patients with acute carbon monoxide poisoning, especially older adult patients, often have difficulty expressing clinical symptoms due to early consciousness disturbances, making the early identification of complications challenging and leading to delayed diagnosis and treatment. Therefore, exploring indicators that can predict in-hospital cardiovascular adverse events in older adult patients with acute carbon monoxide poisoning -induced myocardial injury has important clinical significance. Therefore, this retrospective cross-sectional study included older adult patients with acute carbon monoxide poisoning-induced myocardial injury at the Department of Hyperbaric Oxygen of Beijing Chao-Yang Hospital from January 2013 to December 2019. A total of 119 older adult patients with acute carbon monoxide poisoning-induced myocardial injury were included in the study, with 94 patients in the nonevent group (54 males, 40 females, 71.09 ± 7.60 years) and 25 patients in the cardiovascular adverse event group (10 males, 15 females, 71.48 ± 10.38 years). Compared with those in the nonevent group, creatine kinase isoenzyme levels, triglyceride levels, the neutrophil/lymphocyte ratio and the monocyte/high-density lipoprotein cholesterol ratio were significantly greater in the cardiovascular adverse event group, and high-density lipoprotein cholesterol levels were significantly lower in the cardiovascular adverse event group. Further binary logistic regression analysis showed that higher monocyte/high-density lipoprotein cholesterol ratio might be an independent risk factor for in-hospital adverse events in older adult patients with acute carbon monoxide poisoning-induced myocardial injury (OR = 109.783, 95% CI: 2.644-4557.834; P = 0.013). The area under the curve of the monocyte/high-density lipoprotein cholesterol ratio in predicting in-hospital cardiovascular adverse events in older adult patients with myocardial injury due to acute carbon monoxide poisoning was 0.797, the cutoff value was 0.645, the sensitivity was 68.0%, and the specificity was 88.2%. The inflammatory indicators monocyte/high-density lipoprotein cholesterol ratio and neutrophil/lymphocyte ratio were identified as an independent risk factor for predicting in-hospital cardiovascular adverse events in older adult patients with acute carbon monoxide poisoning-induced myocardial injury in this study. Specifically, monocyte/high-density lipoprotein cholesterol ratio was identified as an independent risk factor for predicting adverse events during hospitalization.
