*Antenatal ultrasound scans are reported separately from antenatal appointments, as they are usually conducted in two different departments (even though they may be conducted during the same visit to the hospital). ^#These data are estimates based on a study that investigated antenatal visits and scans which recorded a median of 10 (range 1 to 22) visits and 6 (range 1 to 22) ultrasound scans.
