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
Peptide G protein-coupled receptors (GPCRs) for pituitary adenylate cyclase activating polypeptide (PACAP) regulate the growth of non-small cell lung cancer (NSCLC) cells. PACAP binds with high affinity to PAC1, which causes transactivation of receptor tyrosine kinases (RTK) for the EGFR and HER2 but its effect on HER3 is unknown. Using 3 NSCLC cell lines (NCI-H358, NCI-H441, and Calu-3), proteins for EGFR, HER2, HER3, and PAC1 were detected. The increase in EGFR tyrosine phosphorylation caused by PACAP was blocked by the EGFR tyrosine kinase inhibitor (TKI) gefitinib, or PACAP(6-38), a PAC1 antagonist. The increase in HER2 tyrosine phosphorylation caused by PACAP was inhibited by trastuzumab, a monoclonal antibody (mAb) for HER2, or PACAP(6-38). The increase in HER3 tyrosine phosphorylation caused by PACAP was inhibited by HER3 mAb3481 or PACAP(6-38). Immunoprecipitation experiments indicated the PACAP addition to Calu-3 cells resulted in the formation of EGFR/HER3 and HER2/HER3 heterodimers. Addition of the HER3 agonist neuregulin (NRG)-1 increased HER3 tyrosine phosphorylation in non-small-cell lung cancer (NSCLC) cells. PACAP or NRG-1 increased the proliferation of NSCLC cells, whereas PACAP(6-38), gefitinib, trastuzumab, or mAb3481 inhibited proliferation. The results indicate that PAC1 regulates the proliferation of NSCLC cells as a result of transactivation of the EGFR, HER2, and HER3.
