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
Rheumatoid arthritis (RA) is a degenerative joint disease that is caused by multiple pathogenic factors. However, the precise etiology of RA is still unknown. Our previous studies demonstrated that acid-sensing ion channel 1a (ASIC1a)-mediated articular chondrocyte apoptosis played a key role in the progression of RA. In this study, we aim to explore whether ASIC1a mediates autophagy or not and the effect of autophagy on ASIC1a-mediated apoptosis. Primary articular chondrocytes, extracted from rat knee joints, were exposed to different concentrations of concentrated hydrochloric acid for different time intervals in vitro. The results indicated that extracellular acid treatment induced autophagy of rat articular chondrocytes. Moreover, inhibition of ASIC1a with either psalmotoxin 1 or ASIC1a short hairpin RNA reduced the autophagy flux. The results suggested that ASIC1a mediated acid-induced autophagy. Pretreatment with autophagy antagonist 3-methyladenine decreased the autophagy, but increased the apoptosis mediated by ASIC1a. Furthermore, knockdown of Beclin 1 by small interfering RNA attenuated autophagy but potentiated ASIC1a-mediated apoptosis of rat articular chondrocytes. Taken together, these findings suggested that both inhibition and silencing of autophagy could enhance ASIC1a-mediated apoptosis in rat articular chondrocytes, and therefore, autophagy is likely to be a new mechanism involved in ASIC1a-mediated apoptosis of articular chondrocytes during the pathogenesis of RA.
