Data presented as median (IQR).
Telelphone clinic intervention group n=30; control group n=57, Quality of Life questionnaire responses n=55.
CDAT score range 7–35. Knowledge score range 1–17; GF foods only scores 0–7, higher scores indicate better knowledge. CDAQ score range 1–100, with a higher score reflecting better quality of life.
