Six-year follow-up of pancreatic β cell function in adults with latent autoimmune diabetes

Table 2 Correlation analysis of the average decreased percentages of FCP per year in LADA patients.

	GAD-Ab Index	Age at onset (yr)	BMI (kg/m2)	Sex (m/f)	Duration (yr)	Family history	FBG (mmol/L)	HbA1c (%)
Correlation efficient	0.408	–0.301	–0.523	0.19	–0.084	–0.198	0.132	–0.035
P	0.006	0.047	0.000	0.216	0.590	0.197	0.430	0.835

The correlations between variables at entry including GAD-Ab index, age at onset, BMI, sex, duration, family history, FBG, HbA1c and the average decreased percentages of FCP per year in LADA patients were analyzed. And GAD-Ab index, age at onset and BMI were found to be the three significant variables (r = 0.408, -0.301 and -0.523, P = 0.006, 0.047 and 0.000).
