Regressions include controls for age, gender and province of birth.
Of these, 30 AI patients were matched to controls for age and sex.
Excluding both the controls for age effects and time-invariant unobservables would have increased this bias to (0.2~%).
I extend their approach to control also for time-variant unobserved factors by including controls for age.
Patients with AI were matched to controls for age and sex using the Optimal Matching method from the MatchIt package of R statistics [21].
The equation also includes the unemployment rate, controls for age and education as well as region, time and occupation fixed effects.
b OLS regressions include additional controls for age, years of education, marital status, total net household income in 10,000 s Euros and body height.
