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
Hepatic sinusoidal obstruction syndrome (HSOS) is a serious side effect of oxaliplatin (OXA) treatment. The present study aimed to establish a reproducible mouse model of OXA‑induced HSOS and to preliminarily explore the underlying molecular mechanisms using mRNA microarray analysis. A total of 45 C57BL/6 male mice were randomly divided into five groups: Control, 5 mg/kg OXA, 10 mg/kg OXA, 15 mg/kg OXA and 20 mg/kg OXA. The mice were respectively injected intraperitoneally with 5% glucose solution, or 5, 10, 15 or 20 mg/kg OXA solution once a week for 6 consecutive weeks. The body weight of the mice was recorded every day. The serum levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were determined. Hematoxylin and eosin staining, Sirius red staining and scanning electron microscopy were used to identify pathological changes. mRNA microarray was used to analyze changes in the gene expression profiles mainly from the functional aspects of Gene Ontology and the Kyoto Encyclopedia of Genes and Genomes. The oxidation mechanism was verified by measuring oxidative stress‑related markers and reactive oxygen species with dihydroethidium probe technology, according to the microarray results. Among all of the OXA groups, 10 mg/kg OXA resulted in an acceptable survival rate of 78%. The mice showed obvious splenomegaly, increases in serum levels of ALT and AST, aggravation of liver pathological injuries and hepatic sinusoidal injuries. The microarray results suggested that mRNA expression changes after OXA treatment were associated with 'oxidative stress', 'coagulation function', 'steroid anabolism' and 'pro‑inflammatory responses'. The results confirmed that OXA aggravated oxidative damage in the livers of the mice. The present study successfully established a mouse model of OXA‑induced HSOS and preliminarily analyzed the underlying molecular mechanisms involved, thus laying a foundation for a subsequent in‑depth study.
