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 investigate the effect of manipulation treatment on knee osteoarthritis rats and the effect on Rho-associated protein kinase (ROCK)/LIM-kinase1 (LIMK1)/Cofilin signaling pathway.
methodFifty Specific pathogen Free Sprague-Dawley rats were randomly divided into five groups ( = 8 each): blank group, model group, manipulation group, celecoxib group, and manipulation combined with celecoxib group (MC group). The osteoarthritis model was established by injecting 0.2 mL 4% papain into the articular disc of the rats. After successfully establishing the model, we treated the manipulation group with pushing manipulation using one-finger-meditation to the Neixiyan (EX-LE4), Waixiyan (EX-LE5), Xuehai (SP10), Liangqiu (ST34), and Zusanli (ST36) acupoints for 10 min each time. Also, the celecoxib group was gavaged with 24 mg•kg•d celecoxib, while the MC group was treated using both of these two methods. After four weeks, the cartilage of the right femur was removed for hematoxylin-eosin staining of the cartilage tissue. The expressions of interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α) in serum were observed using the enzyme-linked immunosorbent assay. Besides, we detected the expressions of ROCK, LIMK1, Phospho-LIM-kinase1 (Phospho-LIMK1), Cofilin, and Phospho-Cofilin by Western blot.
resultsCompared to the model group, the manipulation group, celecoxib group, and MC group all exhibited superior results concerning pathological morphologic changes of cartilage, as observed by hematoxylin-eosin staining and calculated using the Mankin score. Besides, in contrast to the blank group, the model group exhibited elevated serum levels of IL-1β and TNF-α ( 0.01), while the expression of ROCK, LIMK1, Phospho-LIMK1, Cofilin, and Phospho-Cofilin in cartilage were all higher ( 0.01). Also, the serum levels of IL-1β and TNF-α in each treatment group were lower (0.01) than in the model group. Moreover, there were lower expressions of ROCK, LIMK1, Phospho-LIMK1, Cofilin, and Phospho-Cofilin in cartilage in the manipulation group and the MC group (< 0.01). Compared with the model group, the expression of ROCK, LIMK1, Phospho-LIMK1, Cofilin, and Phospho-Cofilin in cartilage in the celecoxib group were not statistically different ( > 0.05).
conclusionIn this study, we established that manipulation has a better curative effect than celecoxib. Manipulation inhibits the development of cytoskeleton damage in cartilage and slows articular degeneration by regulating the expression of related proteins in the cytoskeletal signaling pathway.
