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
backgroundThis study aimed to investigate the associations between pain intensity, hypervigilance and catastrophising with specific cognitive domains in patients with chronic painful temporomandibular disorders (TMD), focusing on identifying cognitive deficit domains.
methodsA cross-sectional study was conducted with a sample of 80 participants (41 chronic painful, 39 controls). TMD was diagnosed according to the Diagnostic Criteria for TMD. Cognitive performance was assessed using the Montreal Cognitive Assessment (MOCA), while pain-related factors were evaluated using the Pain Vigilance Awareness Questionnaire, the Pain Catastrophizing Scale and Pain Intensity. Statistical analyses included independent t-tests to compare group means, followed by multiple regression analysis to examine the associations between cognitive domains and pain-related variables.
resultsCompared to controls, TMD patients showed significantly lower MOCA scores in visuospatial/executive functioning (mean difference = 3.3, p = 0.03), attention (mean difference = -2.5, p < 0.002) and memory (mean difference = -1.8, p = 0.001). Higher pain intensity was significantly associated with visuospatial/executive deficits (β = -0.34, 95% CI: -0.50 to -0.18; p < 0.001), while catastrophising was strongly linked to reduced attention (β = -0.05, 95% CI: -0.08 to -0.02; p < 0.001). Hypervigilance showed a significant negative correlation with memory performance (β = -0.04, p = 0.003).
conclusionsOur study reveals that chronic painful TMD is associated with some cognitive impairments, particularly in visuospatial/executive functioning, attention and memory. Elevated pain intensity and catastrophising emerged as the most impactful factors, closely linked to deficits in these cognitive domains. These findings identify executive control, attention and memory as the cognitive domains most vulnerable to the influence of chronic pain in TMD patients. SIGNIFICANCE: This study provides novel insights into the cognitive impairments associated with chronic painful TMD. By demonstrating strong associations between pain intensity, hypervigilance and catastrophising with deficits in executive function, attention and memory, our findings highlight the cognitive burden of chronic TMD. These results underscore the necessity of integrating cognitive and psychological assessments into clinical management, fostering a more comprehensive approach to treatment that extends beyond pain relief to improving cognitive function and overall quality of life.
