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
purposeEsophageal cancer (EC) is a rapidly progressing malignancy characterized by a low survival rate and limited treatment success, largely due to late-stage detection, frequent recurrence, and a high propensity for metastasis, despite ongoing advances in therapeutic strategies. While oxaliplatin (L-OHP) is a potent chemotherapeutic agent that induces apoptosis in EC cells, its effectiveness is significantly hindered by the development of resistance. MATERIALS AND
methodsThe assessment of gene and protein expression was conducted through a combination of quantitative real-time polymerase chain reaction, Western blot, and immunohistochemical staining. Cell viability was assessed using the cell counting kit-8 assay. The interactions among ALYREF, TBL1XR1, KMT2E, and APOC1 were investigated through RNA immunoprecipitation, chromatin immunoprecipitation (ChIP), ChIP-reChIP, RNA pulldown, and dual-luciferase assays. An in vivo mouse model of EC was established.
resultsExpression levels of both APOC1 and ALYREF were elevated in L-OHP-resistant EC tissues and cell lines, and their silencing enhanced sensitivity to L-OHP. TBL1XR1 and KMT2E synergistically upregulated APOC1 expression. Moreover, ALYREF recognized the 5-methylcytosine (m5C) sites on TBL1XR1 and KMT2E mRNAs, stabilizing these transcripts and promoting APOC1 expression. The regulatory role of these interactions was further validated in vivo.
conclusionThis study demonstrated that ALYREF interacted with the m5C sites on TBL1XR1 and KMT2E mRNAs, enhancing their stability and leading to increased transcription of APOC1, which in turn contributed to L-OHP resistance in EC. These findings suggest that targeting APOC1 could be a promising strategy for overcoming L-OHP resistance in EC.
