Protective Effect of Norcantharidin on Collagen-Induced Arthritis Rats.
Article in Chinese journal of integrative medicine, 2018. 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
objectiveTo observe the effect of norcantharidin (NCTD) on collagen-induced arthritis (CIA) rats.
methodsSixty Sprague-Dawley(SD) rats were randomly divided into 6 groups (n=10): normal group, CIA model group(model group), NCTD low-dose group [1.35 mg/(kg•d)], NCTD middle-dose group [2.7 mg/(kg•d)], NCTD high-dose group [5.4 mg/(kg•d)] and methotrexate (MTX) group [1.8 mg/(kg/w)]. Anesthetized rats were sacrificed by luxation of cervical vertebra after 4 weeks of administration. The arthritis scores were evaluated twice a week. The pathological changes in the ankle joints of rats were observed by hematoxylin-eosin (H&E) staining. The serum levels of interleukin (IL) 1β, IL-6, tumor necrosis factor (TNF)-α, vascular endothelial growth factor (VEGF), IL-17 and transform growth factor (TGF) β were detected by enzyme linked immunosorbent assay (ELISA). The mRNA expression of retinoid-related orphan nuclear receptorγt (RORγt) and forkhead box P3 (Foxp3) in peripheral blood lymphocytes were confirmed by real-time polymerase chain reaction.
resultsMTX and high-dose NCTD not only decreased the arthritis scores but also alleviated the pathological changes in CIA rats' ankle joints compared with the model group (P<0.05 or P<0.01). All doses of NCTD significantly inhibited the serum levels of IL-6, IL-17 and TNF-α in CIA rats (P<0.05). Only middle- and high-dose of NCTD prominently decreased serum IL-1β and TGF-β levels of CIA rats (P<0.05). However, NCTD has no effect on vascular endothelial growth factor (VEGF) level in CIA rats. The Foxp3 mRNA expression in all NCTD groups were increased significantly than in the model group (P<0.05). The mRNA expression of RORγt in NCTD high-dose group was decreased apparently in comparison with the model group (P<0.05).
conclusionsNCTD showed therapeutic effect on CIA rats by inhibition of cytokines and regulation of Th17/Treg cells.
