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
backgroundPost-translational modification pathway of protein ubiquitination is intricately associated with tumorigenesis. We previously reported elevated ubiquitin-conjugating enzyme 2T (UBE2T) as an independent risk factor in stage I lung adenocarcinoma and promoting cellular proliferation. However, its underlying mechanisms needed further investigation.
methodsImmunohistochemistry was used to assess the expression of UBE2T and retinoic acid receptor-related orphan receptor α (RORA) in stage I LUAD. Cell proliferation, migration, and invasion of LUAD cell lines were measured by Cell Counting Kit-8 assay (CCK-8), Colony-forming assay and Transwell assay, respectively. Western blot analysis was performed to determine the expression of epithelial-mesenchymal transition (EMT) markers. A xenograft model was established to evaluate the proliferative capacity of UBE2T and its interaction with RORA in promoting LUAD. Mechanistic insights into the promotion of early-stage LUAD by UBE2T were obtained through luciferase reporter assay, chromatin immunoprecipitation and co-immunoprecipitation.
resultsUBE2T and RORA expression was significantly up- and down-regulated in early-stage LUAD patients which's proved to be associated with unfavorable outcomes, strengthened cell proliferation, migration, EMT and invasion through its interaction with RORA both in vivo and in vitro. The growth NSCLC xenografts was reduced by down-expression of UBE2T but was suppressed by RORA knockout. Mechanistically, UBE2T mediated the ubiquitination of the intermediate transcription factor PBX1, which played a transcriptional role in downstream regulation of RORA.
conclusionThe oncogenic role of UBE2T and the UBE2T-PBX1-RORA axis in driving malignant progression in Stage I LUAD had been established. UBE2T might be a novel and promising therapeutic target for LUAD treatment.
