Association Between Symptomatic Knee Osteoarthritis and Target Glycemic Control in Individuals With Type 2 Diabetes.
Article in Arthritis care & research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveKnee osteoarthritis (OA) commonly affects individuals with type 2 diabetes (T2DM) and is associated with increased risk of diabetes-related complications. To better understand potential mechanisms, we examined the association between symptomatic knee OA and glycemic control in individuals with T2DM.
methodsIn this cross-sectional study, we recruited individuals with T2DM aged ≥45 years from three academic centers in Canada. Online questionnaires assessed demographics, medical history, and joint symptoms. We abstracted glycosylated hemoglobin (HbA1c) from clinic records. Knee OA was defined as fulfilling the National Institute of Clinical Excellence criteria. Target glycemic control was defined as an HbA1c level ≤7.0%. Multivariable logistic regression assessed the association between knee OA and target glycemic control, adjusting for age, gender, education level, and body mass index. Secondary analyses assessed associations between knee OA with pain ≥20/100 (and knee OA with walking difficulty) and target glycemic control.
resultsAmong 351 participants (mean age 66.2 years, 50.7% women), 28.5% met the criteria for knee OA and 43.9% were at glycemic target. In unadjusted analyses, those with knee OA had lower odds of being at target glycemic control (odds ratio [OR] 0.60, 95% confidence interval [CI] 0.37-0.97), but the association was not statistically significant after adjusting for confounders (OR 0.65, 95% CI 0.39-1.08). In those with knee OA with pain ≥20/100, a negative association with target glycemic control was statistically significant in adjusted analysis (OR 0.58, 95% CI 0.34-0.99).
conclusionIndividuals with T2DM and painful knee OA are less likely to be at glycemic target, increasing their risk of diabetes complications.
