Dietary supplementation of vitamin B1 prevents the pathogenesis of osteoarthritis.

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
As the primary cause for chronic pain and disability in elderly individuals, osteoarthritis (OA) is one of the fastest-growing diseases due to the aging world population. To date, the impact of microenvironmental changes on the pathogenesis of OA remains poorly understood, greatly hindering the development of effective therapeutic approaches against OA. In this study, we profiled the differential metabolites in the synovial fluid from OA patients and identified the downregulation of vitamin B1 (VB1) as a metabolic feature in the OA microenvironment. In a murine destabilization of medial meniscus-induced OA model, supplementation of VB1 significantly mitigated the symptoms of OA. Cytokine array analysis revealed that VB1 treatment remarkably reduced the production of a pro-OA factor-C-C Motif Chemokine Ligand 2 (CCL2), in macrophages. Further evidence demonstrated that exogenous CCL2 counteracted the anti-OA function of VB1. Hence, our study unveils a unique biological function of VB1 and provides promising clues for the diet-based treatment of OA.
