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
objectiveTo investigate the correlation of glial-lymphatic (glymphatic) system function with cognitive deficits in non-small cell lung cancer (NSCLC).
methodsData (demographic, clinical, and magnetic resonance imaging [MRI] information) from 83 NSCLC cases and 96 healthy controls were retrospectively analyzed. We evaluated glymphatic activity by using the diffusion tensor imaging analysis along the perivascular space (DTI-ALPS) index and cognitive function with the Montreal Cognitive Assessment (MoCA). Medial Temporal Atrophy (MTA) and Fazekas scores were also rated. Statistical analyses included inter-group comparisons, partial correlation assessments, mediation modeling, and regression to identify predictors of cognitive impairment.
resultsNSCLC patients had higher MTA and Fazekas scores but lower MoCA and ALPS index scores than controls (all P < 0.05). The ALPS index was symmetrically reduced in both hemispheres, correlating positively with MoCA (r = 0.276, P = 0.012). In the mediation model, the ALPS index exhibited a partial mediating role (4.6%) in the NSCLC-MoCA association. Older age was an independent predictor of cognitive impairment (odds ratio [OR]: 1.229; 95% confidence interval [CI]: 1.111-1.360).
conclusionIn NSCLC patients, glymphatic dysfunction was associated with cognitive impairment, and the DTI-ALPS index may facilitate early detection of these deficits. Advanced age remains a major contributing risk factor.
