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
backgroundNLRP3 (NOD-, LRR- and pyrin domain-containing protein 3)-induced pyroptosis is involved in the development of a variety of autoimmune diseases, but its role in IgG4-related sialadenitis (IgG4-RS) is unclear.
methodsSalivary gland tissues from 19 patients with IgG4-RS were designated the experimental group, and peritumoral tissues from 20 patients with benign salivary gland tumours were designated the control group. The cell morphology and fibrosis in the IgG4-RS samples were observed by haematoxylin-eosin (H&E) and Masson trichrome (MT) staining. Immunohistochemical (IHC) staining was used to determine pyroptosis-related proteins (NLRP3, ASC (apoptosis-associated speck-like protein containing a CARD), Caspase-1, GSDMD (gasdermin family members, including digestive dermatin D), interleukin 1β (IL-1β), and interleukin 18 (IL-18)) expression levels.
resultsIncreased lymphoid follicle proliferation, germinal centre plasma cell infiltration, and irregular fibrosis were observed in the experimental group compared with the control group. The NLRP3, ASC, Caspase-1, GSDMD, IL-1β, and IL-18 levels were significantly higher in the experimental group than in the control group (p < 0.0001).
conclusionThis study suggested that pyroptosis-related proteins might be involved in IgG4-RS pathogenesis. However, the specific cellular pathway involved and whether multiple cell death pathways contribute to the occurrence of IgG4-RS still need to be further studied.
