The Clinico-Radiological Effect of Vitamin D in Treatment of Osteoarthritis of the Knee: A Randomized Control Trial.
Article in Journal of orthopaedic case reports, 2025. 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
Introduction: Vitamin D treatment reduces osteoarthritis (OA) pain, inflammation, and cartilage degradation, indicating that it may have therapeutic advantages in the management of OA symptoms. Thus, the present study was conducted to assess the effect of Vitamin D in treatment of Knee OA. Materials and Methods: A randomized control study was done on 78 cases, fulfilling American College of Rheumatology criteria for diagnosis of OA knee. Patients were randomized into an experimental (vitamin D supplement along with standard treatment for Knee OA [KOA]) and placebo group (standard treatment for KOA). All patients were followed up from baseline till 12 months. Pain was assessed using Visual Analog Scale (VAS) and functional outcome by Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score. Cartilage thickness of medial, sulcus, and lateral femoral condyle was evaluated at baseline and after a year using ultrasound imaging. Data collected and recorded on MS Excel. Data were analyzed using the Statistical Package for the Social Sciences version 20.0 software. Results: Mean VAS and WOMAC score were comparable (P > 0.05), but less in experimental than placebo group at all-time intervals. Average cartilage thickness of medial and lateral femoral condyle was comparable (P > 0.05), but more in experimental than placebo group. Average cartilage thickness of sulcus femoral condyle was considerable (P < 0.05) and more in experimental than placebo group at 12 months. Thickness of cartilage decreased in both groups from baseline to 12 months; but not considerably (P > 0.05) in experimental group. Conclusion: Patients with OA discomfort in their knees were benefited in terms of pain and functionality, after taking Vitamin D supplements. There is a necessity of standardized, carefully planned studies to gain a deeper understanding of vitamin D's function in KOA treatment.
