Osteopontin can decrease the expression of Col-II and COMP in cartilage cells in vitro.
Article in International journal of clinical and experimental medicine, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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 osteopontin (OPN) on the expression of collagen type II (Col-II) and oligomeric matrix protein COMP in cartilage cells of knee osteoarthritis, and explore the mechanism of OPN in the knee osteoarthritis.
methodsCartilage cells were isolated from fetal rabbit, they were divided into 3 groups: A (control); B (0.5 μM OPN) and C (1 μM OPN). The expression levels of Col-2 and COMP were detected by RT-PCR and Western blotting methods. MMP-13 was detected using ELISA. The proliferation was determined by MTT method.
resultsCompared with the group, the expression levels of Col-2 and COMP in cartilage cells decreased in the intervention group with dose dependent (P<0.05). The expression of MMP-13 in culture supernatant and the proliferation increased in the intervention group (P<0.05).
conclusionOPN can down-regulate the expression levels of Col-2 and COMP in cartilage cells and up-regulate the expression of MMP-13 in culture supernatant and promote the proliferation of cells, which could accelerate the pathological process of cartilage cells.
