1 · What the graph read from it

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.

2 · The registry

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 melatonin intervention on rat knee osteoarthritis (KOA) model and explore its mechanism.

methodsA total of 81 Sprague-Dawley (SD) rats were employed. Haematoxylin and eosin (H&E) staining and safranin o-solid green staining were used to observe the changes of pathology in KOA, and inflammation factors in serum were detected by enzyme-linked immunosorbent assay (ELISA), type II collagen (Col-II) was detected by immunohistochemistry, chondrocyte apoptosis was detected by TdT-mediated dUTP nick-end labeling (TUNEL). The expression of matrix metalloproteinases (MMPs) and JAK2/STAT3 signaling were detected by western blot.

resultsMelatonin treatment ameliorated the histomorphology of knee joint in rats compared to the model group. The contents of TNF-α, IL-6, and IL-1β in serum were decreased after melatonin treatment. In addition, compared to the model group, the positive expression of Col-II increased, the chondrocyte apoptosis decreased after melatonin treatment. Interestingly, the expression levels of MMP3, MMP9, MMP13, p-JAK2 and p-STAT3 decreased (p < 0.05). Importantly, melatonin combined with AG490 is significantly ameliorates histomorphology of knee joint, reduced cartilage loss compared with melatonin treatment alone.

conclusionsMelatonin treatment can effectively diminish the cartilage injury. Its mechanism may be related to protect the articular cartilage by reducing the release of inflammatory factors, inhibit the expression of MMPs and JAK2/STAT3 signaling.
