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
objectivesInterleukin (IL)-33 plays an important role in host defense, immune regulation, and inflammation. This study assessed IL-33's role in the pathogenesis of severe hemolytic uremic syndrome (HUS) induced by enterohemorrhagic Escherichia coli (EHEC). We also investigated the clinical significance of IL-33 and soluble ST2 (soluble form of IL-33 receptor) serum levels in patients with EHEC-induced HUS.
methodsThe role of IL-33 in Shiga toxin (STx)-2-induced endothelial injury was studied in human umbilical vein endothelial cells (HUVECs) in vitro. Blood samples were obtained from 21 HUS patients and 15 healthy controls (HC). The IL-33 and sST2 serum levels were quantified using an enzyme-linked immunosorbent assay. The results were compared to HUS' clinical features.
resultsCytotoxic assays indicated that IL-33 enhanced STx2 toxicity in HUVECs. Serum IL-33 levels in most HUS patients were below the lowest detection limit. On the other hand, serum sST2 levels in patients during the HUS phase were significantly higher than those in HC and showed a correlation with disease severity. Serum sST2 levels in patients with encephalopathy were significantly higher than those in patients without it. A serum sST2 level > 63.2 pg/mL was associated with a high risk of encephalopathy. Serum sST2 levels significantly correlated with serum levels of inflammatory cytokines related to the development of HUS.
conclusionsOur results indicate that IL-33 contributes to the severity of EHEC-induced HUS. Serum sST2 level in HUS patients correlated with disease activity, which suggests its potential role as a marker for disease activity and development of encephalopathy in patients with EHEC-induced HUS.
