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
Fibroblast activation protein (FAP) is a quinoline-based membrane bound glycoprotein enzyme. It is not expressed in normal adult tissue except for the myometrium and sometimes in pancreas. The expression increases in inflammation and in cancer-associated fibroblasts. Gallium 68-FAP inhibitor (FAPI) is known to localize in various neoplasms by the virtue of their property of cancer-associated fibroblast activity. Fibroblasts are also known to be associated in inflammatory and infectious condition such as cholecystitis, pyelonephritis, and tuberculosis. Immunoglobulin G4 related disease (IgG4RD) is characterized by infiltration of various tissues with IgG4-rich lymphoplasmacytic fibrotic tissue and has been reported to express cancer-associated fibroblast. The time-tested molecule for cancer imaging F18-fluorode-oxyglucose requires 4-6 h of fasting state. Ga68-FAPI does not require fasting. This pictorial essay illustrates various entities, cancerous as well as noncancerous using Ga68-FAPI positron emission tomography computed tomography (PET CT) imaging.
