Characterization of the epidemiology, susceptibility genes and clinical features of viral infections among children with inborn immune errors: a retrospective study.
Article in Virology journal, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 2 papers.
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
backgroundAlthough viral infections are one of the common clinical manifestations in patients with inborn errors of immunity (IEIs), little is known about the epidemiology, susceptibility genes, and clinical status of viral infections in patients with IEIs.
methodsThe demographic information, clinical diagnoses, and laboratory findings of 931 IEI patients who underwent viral testing from January 2016 to December 2022 were collected and analyzed.
resultsIn total, 47.15% (439/931) patients with IEI tested positive for at least one virus during hospitalization. There were a total of 640 viral infections during the study period, mainly from EBV 131 (20.47%), HRV 102(15.94%), CMV 100(15.63%), and RV 84(13.13%). CMV and RV infections were more common in the combined immunodeficiencies (IEI_I) group during the infant stage, whereas EBV infection was more common in the immune dysregulation (IEI_IV) group during the preschool stage. Mutations in SH2D1A (57.14%), PIK3CD (56.41%) and LRBA (50%) make individuals susceptible to EBV infection; mutations in WAS (30%) make individuals susceptible to CMV infection; and mutations in IL2RG (56.52%) and RAG1 (37.5%) make individuals susceptible to RV infection. Joinpoint analysis revealed trends in viral positivity in different years.
conclusionThese data suggest that it is possible to target the prevention, treatment, and management of IEI patients who are infected with a virus by accounting for the age at infection, type of IEI, and mutant genes, but special attention needs to be paid to viral infections in IEI_I and IEI_IV patients during the infant stage.
