Range of published narcolepsy prevalence estimates

from 1.05 to 79.40 per 100,000 population

people per 10,000, 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.”

What to know
The span across 35 studies, not a pooled figure: the authors conclude the estimates could not be pooled reliably.
Arithmetic
1.05 and 79.40 per 100,000 / 10 = 0.105 and 7.94 per 10,000
