  • * SLE hospitalizations per 100,000 children in population aged 2 to 21 years, based on population estimates from US Census data.

  • ** Outcomes evaluated for temporal trend using multivariable regression to adjust for patient and hospital-specific demographic variables (with the exception of hospitalization rate, which was evaluated by univariable regression). SLE: systemic lupus erythematosus; LOS: length of stay.
