Mean, median and range were calculated per group of problem events.
A: Problem events with appropriate ICPC codes for pneumonia (R78, R80, R81, R95, R99); diabetes (A91, F83, F92, L99, N94, T87, T90, T99, U99, W84); tonsillitis (R72, R76, R90); and anaemia (A85, B74, B78, B79, B80, B81, B82, B99, T91).
I: Problem events with inappropriate ICPC codes for pneumonia (D01, U88, R74, R96); diabetes (D01, D11, D70, K77, F29); tonsillitis (D01, R21, R24); and anaemia (D01, L84).
SD: Standard Deviation; SE: Standard Error of the Mean.
