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
backgroundLactate, as an end product of glycolysis, plays an important role in cellular metabolism and signal transduction, and recent studies have shown that it is closely related to cellular differentiation, but its potential role in osteogenic differentiation has not yet been fully investigated.
methodsWe obtained two datasets containing human mesenchymal stem cells and human osteoblasts, GSE12266 and GSE18043, from the GEO database, which contained a total of 14 samples with sequencing data, and searched for lactate metabolism-related genes from the Genecards database. Ten differentially expressed core genes related to lactate metabolism were identified by differential expression analysis, protein interaction network analysis, and correlation expression analysis, and determined to play a key role in osteogenic differentiation. The effects of hub genes on the immune microenvironment of osteogenic differentiation were explored by enrichment analysis and immune infiltration analysis, and the significant effects of the key gene TYRO Protein Tyrosine Kinase-Binding Protein(TYROBP) on the characterization of bone marrow mesenchymal stem cells (BMSCs) were experimentally verified, and it was determined by drug sensitivity analysis that TYROBP may be a regulatory target of certain drugs affecting osteogenic differentiation.
resultWe successfully screened 10 differentially expressed hub genes related to lactate metabolism, and their area under the curve AUC values for predicting osteogenic differentiation were all highly favorable. Enrichment analysis showed that lactate metabolism may affect osteoblast differentiation through immune infiltration, and the immune infiltration results confirmed the strong association between hub genes and osteoblast immune infiltration status. It was verified that decreasing TYROBP expression promoted cell viability, proliferation and migration ability of BMSCs. Drug sensitivity analysis showed that TYROBP may be a major regulator of drug-induced MSC differentiation.
conclusionOur study reveals the critical role of lactate metabolism in osteoblast differentiation, identifies the role of the key gene TYROBP in the regulation of BMSCs, and provides new insights for studies related to the regulation of osteoblast differentiation.
