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
Hypertrophic cardiomyopathy (HCM) is the common cause of sudden cardiac death in young people and is characterized by cardiac hypertrophy. Non-HCM caused left ventricular hypertrophy (LVH) is more common in the population, especially in people with hypertension, obesity, and diabetes. In order to identify high-risk populations, a screening technique that can rapidly differentiate between HCM and LVH patients should be developed. Plasma metabolomics may help develop useful biomarkers for the disease diagnosis. We performed a comprehensive plasma metabolomic analysis on a total of 720 individuals, included 441 HCM patients, 160 LVH patients, and 119 normal controls (NC) (derivation cohort = 368, validation cohort = 352). Orthogonal partial least squares discriminant analysis (OPLS-DA) was used to construct discriminant models based on metabolomics, and the result showed significant changes in plasma metabolic profiling among the HCM, LVH, and NC. The prospective diagnostic biomarkers for HCM patients have been examined using variable importance in projection, fold change, and FDR. Acylcarnitines efficiently distinguished HCM and LVH patients, with a C14:0-carnitine AUC of 0.937 shown by the reiver operator characteristic (ROC) curve analysis. The biomarkers for the diagnosis of HCM patients was verified in another independent validation cohort. This study is the largest plasma metabolomics analysis of Chinese Han patients with HCM, finding biomarkers that can be used to distinguish between HCM from LVH patients. These results highlight the great potential value of plasma metabolic profiling analysis on HCM diagnoses.
