Range of published narcolepsy incidence estimates

from 0.06 to 6.56 per 100,000 person-years

new cases per 10,000 person-years, worldwide

“The estimates of incidence and prevalence were wide-ranging with high heterogeneity (incidence I2 = 99.8%; prevalence I2 = 99.7%), from 0.06 to 6.56 per 100,000 person-years for incidence and from 1.05 to 79.40 per 100,000 population for prevalence, respectively.”
