P(E) | HR0 | HRa | PAF | |
---|---|---|---|---|
The proportion of transport accidents attributable to off medication among ADHD patients | 80%a | 1.41b | 2.38b | 49% |
63%c | 1.41 | 2.38 | 41% |
Abbreviation: P(E): proportion of exposed in the population; HR0=unadjusted Hazard ratio; HRa=adjusted Hazard ratio. PAF was calculated as , see eMethods for details.
Among male ADHD patients, 80% were off medication on average during the follow-up.
for protective effect, reciprocals of HR0 and HRa were used to calculate the PAF of not being exposed to the protective factor (i.e., 1.41=1/0.71, and 2.38=1/0.42).
Among male ADHD patients, 63% were off medication at the end of follow-up.
