  • Values in bold are p>0.05, that is, evidence is not strong enough to show equivalence.

  • *p Value for comparison with Chinese reference population.

  • †Weighted to account for design bias in the DSP.

  • BMI, body mass index; BP, blood pressure; DSP, Disease Specific Programme; HbA1c, glycosylated haemoglobin.
