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
objectiveTo uncover the biological foundation of the prevailing TCM syndrome in individuals with Esophageal squamous cell carcinoma (ESCC), Zhengxu Xieshi (ZXXS), which is characterized by a deficiency in vital
methodsWe investigated shifts in vital
resultsSerum metabolomic profiling highlighted the prevalent downregulation of differentially expressed metabolites in patient sera, in contrast to the upregulation observed in ESCC tissues, compared to their respective controls. Remarkably, the group of differential metabolites in the ESCC tissues was predominantly composed of amino acids. Thus, we focused on amino acid metabolism. Our integrative analysis showed the downregulation of a significant majority of disturbed amino acids in patient sera relative to the upregulation of an overwhelming proportion of perturbed amino acids within ESCC tissues. Enrichment analysis of these amino acids revealed seven metabolic pathways that contribute to the metabolism of antioxidants, energy intermediates, and biosynthetic precursors. Interestingly, these pathways displayed attenuation in patient sera but augmentation in ESCC tissues. Similarly, the proteomic data confirmed the activation of these pathways in ESCC tissues.
conclusionThis study presents a new perspective on the prevalence of ZXXS syndrome in patients with ESCC, contextualized within the realm of metabolic reprogramming. Specifically, diminished amino acid metabolism in the circulating blood corresponds to a deficiency in vital
