Dysregulated PD-L2 is correlated with disease activity and inflammation in rheumatoid arthritis.

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
The programmed death-1 (PD-1) pathway has been shown to deliver an inhibitory signal, and aberrant expression of the PD-1 molecule and/or its ligand programmed death ligand 1 (PD-L1) has been demonstrated in human diseases, while its other ligand, programmed death ligand 2 (PD-L2), has rarely been studied. Here, we investigated the expression of PD-L2 in synovial tissue and blood from patients with rheumatoid arthritis (RA). Soluble PD-L2 and inflammatory cytokine levels in serum among healthy controls and patients with RA were compared via enzyme-linked immunosorbent assay (ELISA). Membrane PD-L2 on monocytes in blood was analyzed through flow cytometry (FCM). The different expression levels of PD-L2 between the RA and non-RA synovium were semi-quantified by immunohistochemical (IHC) staining. The soluble PD-L2 levels in serum from patients with RA were significantly lower than those in healthy subjects, correlating with active parameters (rheumatoid factor) and inflammatory cytokine secretion. The FCM results showed that patients with RA had significantly increased percentages of PD-L2-expressing CD14
