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
purposeAmong malignant tumors, non-small cell lung cancer (NSCLC) remains a major threat to human life and health. Studies have illustrated that minichromosome maintenance protein 4 (MCM4) has complex interactions with the progression of many cancers, yet the role and mechanism of MCM4 in NSCLC remain to be elucidated.
methodsMCM4 expression in NSCLC tissues was assessed using the TCGA database. MCM4 levels in NSCLC cells and tissues was validated utilizing qRT-PCR and western blot. Cell proliferation, metastasis and EMT were measured by CCK-8, transwell, and western blot assays. Subsequently, E2F1 bound with the promoter of MCM4 was predicted via JASPAR database. Luciferase assay and chromatin immunoprecipitation (ChIP) were utilized to evaluate the binding relationship between the two. Finally, rescue experiments were performed to demonstrate the mechanism of MCM4 regulating NSCLC progression. Xenograft model was utilized to prove the role of MCM4 and E2F1 in NSCLC in vivo.
resultsMCM4 was markedly elevated in NSCLC tumor samples and intimately linked to poor patient prognosis. Silencing of MCM4 repressed growth, migration, invasion, and EMT of cells. In vivo test findings displayed that knockdown of MCM4 suppressed changes in tumor volume and weight in mice. Moreover, E2F1 bound with the promoter of MCM4 was predicted by JASPAR database. E2F1 was heightened in NSCLC tissues and cells. Then, the outcome of rescue assays confirmed that E2F1 introduction attenuated the depressing influence of MCM4 knockdown on NSCLC. Moreover, E2F1/MCM4 promoted the progression of NSCLC by activating the PI3K/AKT signaling pathway.
conclusionsE2F1 accelerated NSCLC progression by activating the PI3K/AKT pathway through MCM4. Our outcomes confirmed that MCM4 is a potential target for the treatment of NSCLC patients.
