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
importanceAccurate assessment of osteoarthritis-related pain in dogs requires validated, language-specific clinical metrology instruments. The absence of a Korean version of the widely used Canine Brief Pain Inventory (CBPI) limits standardized pain assessment and outcome evaluation in Korean-speaking clinical and research settings.
objectiveThis study aimed to develop and perform an initial psychometric evaluation of the Korean version of the CBPI.
methodsThis observational cross-sectional study included 56 dogs with osteoarthritis and 22 healthy controls. Construct validity was assessed using exploratory and confirmatory factor analyses. Convergent validity was assessed using Spearman correlations between CBPI scores and the owner-reported quality-of-life item. Discriminant validity was evaluated through group comparisons between dogs with osteoarthritis and healthy controls. Internal consistency was evaluated using Cronbach's α.
resultsExploratory analysis identified a dominant general pain factor (eigenvalue = 8.04; 80.4% variance). Confirmatory factor analysis demonstrated superior relative fit for the two-factor model (χ²/df = 2.94, comparative fit index [CFI] = 0.917, root mean square error of approximation [RMSEA] = 0.186, standardized root mean square residual = 0.044) compared with the one-factor model (χ²/df = 4.13, CFI = 0.861, RMSEA = 0.236). CBPI scores showed significant negative correlations with quality of life in dogs with osteoarthritis (ρ = -0.516 to -0.485; corresponding 95% confidence intervals ranged from -0.710 to -0.248; CONCLUSIONS AND RELEVANCE: The Korean CBPI demonstrated excellent internal consistency and preliminary evidence of construct validity for assessing osteoarthritis-related pain in dogs, supporting its use as an owner-reported outcome measure in Korean-speaking clinical and research settings. Future longitudinal studies should evaluate its test-retest reliability and responsiveness to treatment.
