Background:Clinical features of ARS predict progression of immunosuppression. Here we describe clinical features of ARS by gender and age.

Method:378 patients enrolled in 5 prospective cohorts using similar data, collection forms, and inclusion criteria (Geneva, Lyon, Montreal, Seattle, Sydney) were compared usingc₂test, t-test, and one-way analysis of variance. The correlation was determined between age and duration (days) of AHI with Pearson coefficient.

Results:

Conclusion:Age but not sex is related to clinical features of ARS. That might partially explain the association between age and prognosis.
