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
As one of the most lethal malignant tumors worldwide, the highly invasive and metastatic nature of lung cancer leads to a generally poor prognosis for patients. Among the complications associated with lung cancer, skeletal-related events (SREs) resulting from bone metastases, including bone pain, pathological fractures, hypercalcemia, and spinal cord compression, significantly impair quality of life and reduce survival rates. The long non-coding RNA HOTAIR, which has been linked to various cancers, plays an unclear role in lung cancer bone metastasis and the regulation of the immune microenvironment. In this study, we investigated the expression of HOTAIR in non-small cell lung cancer (NSCLC) and its impact on the immune microenvironment using bioinformatics, microscopy, and functional assays. Our findings indicate that elevated HOTAIR expression is associated with poorer prognosis based on transcriptomic analyses. Bioinformatics validation in independent GEO datasets and clinical tissue samples also confirmed the prognostic value of HOTAIR in NSCLC bone metastasis subgroups. Mechanistically, HOTAIR expression was correlated with alterations in immune cell infiltration patterns, including reduced B-cell and CD8+ T-cell signatures, and was accompanied by increased NF-κB and ERBB pathway activity. These observations suggest that exosome-associated HOTAIR may influence tumor progression-related processes and osteoclast-associated events relevant to bone metastatic progression. Furthermore, the Feiyanning formula (FYN) demonstrated inhibitory effects on tumor growth and metastasis-related phenotypes in experimental models.
