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
backgroundCancer stem cells are essential for the development of tumors, their recurrence, metastasis, and resistance to treatment. Previous studies have shown that the silencing of EBF3 promotes the progression of malignant tumors, but its impact on the stem-like phenotype of tumor cells remains unexplored. Therefore, this work aims to investigate the influence of EBF3 on the stem-like phenotype of breast cancer (BC) cells and its underlying molecular mechanisms.
methodsBioinformatics analysis was utilized to predict EBF3 and miR-301b-3p expression and their binding sites in BC tissues. qRT-PCR was conducted to assess EBF3 and miR-301b-3p expression in BC cells. Cell viability was assessed using CCK-8 assay, while sphere-forming ability was assayed by sphere formation experiments. Western blot analysis was employed to assess the expression of stem cell-related markers and proteins associated with the glycolysis metabolic pathway. ECAR experiments and analysis of glycolysis metabolite production were performed to evaluate cellular glycolysis capacity. Dual-luciferase reporter assays and RIP were utilized to validate the binding relationship between EBF3 and miR-301b-3p.
resultsEBF3 was downregulated in BC tissues and cells, and overexpression of EBF3 repressed the glycolysis capacity of BC cells, thereby suppressing stem-like phenotype. Furthermore, miR-301b-3p was identified as a direct target of EBF3, and its expression was increased in BC. Cell experiments revealed that miR-301b-3p suppressed EBF3 expression, thereby promoting the glycolysis capacity and stem-like phenotype of BC cells.
conclusionmiR-301b-3p enhanced glycolysis and promoted the stem-like phenotype of BC cells by targeting EBF3. These findings can offer new therapeutic approaches for BC.
