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
Background: Snoring, as a common disease, may lead to various cardiovascular diseases. scholars attach importance to the relationship between snoring or sleep breathing disorders and glucose metabolism disorders. Some predictive model for predicting sleep-disordered breathing in patients with diabetes has been developed. Studies have found that blood glucose is an inevitable predictor of the outcome of coronary heart disease. It may mask other predictive factors, leading to clinical neglect of the control of other risk factors. So we developed and validated a nomogram to predict the risk of coronary heart disease in hypertensive patients who snore, excluding those with glucose metabolism disorders. Methods: Records from 2105 snoring patients with hypertension and non-glucose metabolism disorders. A random grouping technique was utilized to split the data into validation and derivation datasets (split ratio = 0.7: 0.3). Least absolute shrinkage and selection operator regression was applied to select predictors and constructed a nomogram model based on multivariate Cox regression analysis. The discrimination and consistency of the nomogram were evaluated using the area under the receiver operating characteristic curve (AUC), calibration plots, and decision curve analysis (DCA) to assess its performance. We found age, male, waist-to-height ratio (WHtR), low and high-density lipoprotein cholesterol (LDL-C and HDL-C), and apnea index (AI) identified as predictors to generate this nomogram model. Results: The C-index at 84 months was 0.703 (95% confidence interval 0.653-0.754) in the derivation set and 0.645 (95% confidence interval 0.562-0.728) in the validation set. The nomogram demonstrated good performance in the calibration curve and DCA. Conclusions: So, our study proposed an effective nomogram model with potential application value for individualized prediction of coronary heart disease outcomes in snoring individuals with hypertension, excluding glucose metabolism disorders. And "AI" was proposed as a novel predictor.
