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
Long non-coding RNAs (lncRNAs) constitute a critical class of regulatory molecules involved in cancer biology and play pivotal roles in tumor initiation and progression. Nevertheless, the biological functions of many newly identified lncRNAs in non-small cell lung cancer (NSCLC), as well as their potential therapeutic relevance, remain insufficiently characterized. In this study, high-throughput sequencing analysis of paired NSCLC tumor tissues and adjacent non-tumorous samples revealed that LINC00973 is significantly upregulated in tumor specimens. Moreover, elevated LINC00973 expression was found to be closely associated with poor clinical outcomes in patients with NSCLC. Functional assays showed that LINC00973 knockdown inhibits NSCLC cell proliferation, migration, and invasion while inducing apoptosis, whereas overexpression produces opposite effects. These observations were confirmed in vivo, where LINC00973 depletion markedly suppressed tumor growth and metastasis. Mechanistically, LINC00973 interacts with and stabilizes deltex E3 ubiquitin ligase 3L (DTX3L), preventing its ubiquitination-mediated degradation and activating the AKT signaling pathway. Therapeutically, RGD-modified exosome-mediated delivery of LINC00973 siRNA significantly inhibited NSCLC progression in mouse models. Moreover, a synthetic biology-based strategy enabling hepatic production of exosomes carrying LINC00973-targeting siRNA achieved robust anti-tumor effects. Together, these findings establish LINC00973 as an oncogenic lncRNA that promotes NSCLC progression via DTX3L stabilization and highlight LINC00973 as a promising therapeutic target.
