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
Early detection and nonintrusive assessment of inflammatory bowel disease (IBD) remain an unmet clinical challenge. Spectral computed tomography (CT) presents a potential modality for gastrointestinal (GI) imaging; however, clinical CT contrast agents are unable to achieve targeted detection of IBD in spectral CT imaging. In this study, we developed neodymium-hyaluronic acid nanoparticles (Nd-HA NPs) as novel contrast agents for spectral CT imaging of IBD. Nd-HA NPs were synthesized by conjugating HA units with lanthanide complex neodymium-diethylenetriamine-pentaacetic acid (Nd-DTPA). The physical properties, biotoxicity, and CT imaging ability of Nd-HA NPs were systematically evaluated in vitro. Subsequently, the applicability of Nd-HA NPs for GI tract imaging was assessed in both healthy and colitis mouse models. Nd-HA NPs exhibited excellent stability, biocompatibility, and potent x-ray attenuation property in vitro as novel spectral CT contrast agents. Attributed to HA's high affinity for cluster of differentiation 44 receptor, which is abundantly expressed at inflammatory sites, Nd-HA NPs successfully achieved targeted spectral CT imaging of IBD, and showed greater accumulation in the lesions of colitis mice compared with the clinical contrast agent iohexol. More importantly, after oral administration of Nd-HA NPs, the CT values of GI tract in healthy mice, 2.5% DSS-induced mice (moderate colitis), and 5% DSS-induced mice (severe colitis) were 90.19, 140.99, and 264.07 HU, respectively, with statistically significant difference (
