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
Lung cancer ranks as the most prevalent malignant neoplasm worldwide, contributing significantly to cancer-related mortality. Stemness is a well-recognized factor underlying radiotherapy resistance, recurrence and metastasis in non-small-cell lung cancer (NSCLC) patients. Our prior investigations have established the role of IQ motif containing GTPase-activating protein 3 (IQGAP3) in mediating radiotherapy resistance in lung cancer, but its impact on lung cancer stemness remains unexplored. Our bioinformatics analysis results revealed a significant correlation between IQGAP3 and lung cancer stemness. Moreover, we found that IQGAP3 depletion in lung cancer cells resulted in reduced migration, invasion and sphere-forming capabilities. Through RNA sequencing, we identified GLI1 as a pivotal downstream effector of IQGAP3. The knockdown of IQGAP3 led to the downregulation of GLI1 mRNA and protein levels, which impeded the activation of the Hedgehog-GLI1 signaling pathway. Further, our results also indicated that GLI1 is the primary effector mediating IQGAP3's biological functions in lung cancer. These findings elucidate the role of IQGAP3 in promoting lung cancer stemness and metastasis through the Hedgehog pathway, facilitated by GLI1, highlighting the potential of IQGAP3 as a promising therapeutic target for lung cancer treatment.
