aStandardised differences of ≥0.1 are considered meaningful.
bEver-present lymphoproliferation, infections and concomitant medications are used in the absence of data variables in the ESID registry.
cHSCT during follow-up represents patients in the cohort who were censored during follow-up though HSCT occurred only after the observation period.
dCytopenias during the leniolisib clinical studies were based on adverse event reports, and were due to any cause (so may not have been due to autoimmunity).
eUsing definition based on any mention of mTOR throughout ESID variables.
Abbreviations: CMV: cytomegalovirus; EBV: Epstein-Barr virus; ESID: European Society of Immunodeficiencies; HSCT: haematopoietic stem cell transplant; IQR: interquartile range; IRT: immunoglobulin replacement therapy; mTOR: mammalian target of rapamycin; NA: not applicable; SMD: standardised mean difference.
