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

Osteoarthritis (OA) is a common and disabling joint disorder that is mainly characterized by cartilage degeneration and narrow joint spaces. The regulatory functions of non-coding RNAs (long non-coding RNAs, microRNAs [miRNAs], and circular RNAs [circRNAs]) in OA progression have attracted considerable attention, and the function of circular RNAs in the context of OA has been an increasingly popular research topic in the last 6 years. Recent studies have reported that various circRNAs can delay or aggravate diverse aspects of the OA process, including extracellular matrix formation, apoptosis, proliferation, inflammation, and autophagy, via circRNA/miRNA/mRNA pathways. Thus, circRNAs and related pathways are potential therapeutic targets for OA. Our review provides comprehensive information about circRNAs, including their biogenesis, functions, and characteristics, and it reveals their critical roles in the pathogenesis of OA via a large regulatory network of sponges. Considering their regulatory functions and characteristics, we hypothesize that circRNAs not only can be transferred through bodily fluids to serve as diagnostic biomarkers, but they can also be released from mesenchymal stem cell-derived exosomes and delivered to OA chondrocytes acting as therapeutic circRNAs. Further investigations of the in-depth molecular mechanisms of action of circRNAs in OA are expected to provide effective and safe OA treatment strategies.
