^* P _{for interaction}=0·008 for HbA1c and water intake between sexes.

^†Model 1=plain water; model 2=model 1+age, ethnic group, BMI, smoking status, qualifications (degree or not); model 3=model 2+total drinks minus plain water (g); model 4=model 3+energy intake, reporter category; model 5=model 4+fibre (g/4184 kJ (g/1000 kcal)).
