CHIP was ascertained based on data of whole exome sequencing. Incident ITP was identified in inpatient hospital records and death register. Cox regression models were utilized to estimate risk of ITP associated with CHIP. We also performed subgroup analyses by CHIP mutations (<jats:italic>DNMT3A<\/jats:italic>, <jats:italic>TET2<\/jats:italic>, <jats:italic>ASXL1<\/jats:italic>, <jats:italic>SRSF2<\/jats:italic>, and <jats:italic>JAK2<\/jats:italic>).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The study included 14,466 and 451,598 individuals with and without CHIP, respectively.

CHIP was associated with an increased risk of ITP (hazard ratio [HR] 2.33, 95% confidence interval [CI]: 1.64\u20133.32).
