Association between vitamin D deficiency, inflammatory markers, and knee osteoarthritis: a retrospective study.
Article in Journal of orthopaedic surgery and research, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundKnee osteoarthritis (OA) is a prevalent condition influenced by various biochemical, anatomical, and lifestyle factors. Vitamin D deficiency has been implicated in OA, but its role in disease severity and associated symptoms remains unclear. We aimed to investigate the prevalence of vitamin D deficiency in knee OA patients and its relationship with inflammatory markers and clinical symptoms.
methodsThis retrospective study analyzed 986 patients with knee OA over a 3.5-year period. Vitamin D levels, ESR, and platelet counts were assessed, along with demographic and clinical data. Statistical analyses were conducted to explore associations.
resultThis study involved 986 patients with knee OA, majority of them (85% ) were female with mean age 52.95 ± 12.44 years. More than half of patients 59.7% had unilateral knee OA and 40.3% had bilateral knee OA. The mean value of Vitamin D3 was 25.35 ± 14.125. Vitamin D deficiency was observed in 70.9% of patients, with moderate deficiency being most prevalent (36.94%). No significant association was found between vitamin D levels and inflammatory markers. However, a strong association was observed between vitamin D deficiency and symptoms like polyarthralgia (p < .05)., Bilateral OA was associated with higher vitamin D deficiency levels compared to unilateral OA (P < .001).
conclusionOA more prevalence among female .As well as, vitamin D deficiency is highly prevalent in knee OA patients and its severity associated with Bilateral OA and polyarthralgia but not with inflammatory markers. Future research should focus on the long-term impact of vitamin D supplementation and the molecular mechanisms underlying these disparities.
