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
The bombesin (Bn) receptor family [Gastrin-releasing peptide (GRPR/BB2R) and Neuromedin B receptors (NMBR/BB1R)] are G-protein coupled receptors (GPCR's) with potent growth effects on normal tissues/numerous cancers, often by transactivating the ErbB receptor-tyrosine kinase (RTK) family. Whereas GRPR stimulation transactivates ErbB RTKs EGFR, HER2, and HER3 in non-small cell lung-cancer (NSCLC) cells, its effects on HER4 are unknown. This study was designed to address this question. Of 12 NSCLC's studied, 75% had HER4 mRNA expression and Western-Blotting. NCI-H522 and NCI-H661-cells had high levels of GRPR, HER4, and the HER4-ligand neuregulin (NRG1). Adding GRP to NCI-H522/NCI-H661-cells activated HER4, shown by its increased phosphorylation (P-HER4). The GRPR antagonists PD176252/BW2258U89 inhibited this increase. In NCI-H661-cells, GRP stimulated the formation of HER4-homodimers and HER2-HER4-heterodimers. Adding GRP to these NSCLC-cells increased P-ERK/P-AKT, which was inhibited by siRNA-HER4, PD176252, and ibrutinib, as well as
