G-Gap was not associated with retinopathy (third tertile versus first or second tertiles of G-Gap: prevalence of retinopathy 50.5 vs. 49.7%; P = 0.972).
G-Gap was not associated with peripheral neuropathy (third tertile versus first or second tertiles of G-Gap: prevalence of neuropathy 48.8 vs. 50.6%; P = 0.827).
Macroproteinuria was the only complication that was associated with G-Gap (prevalence in the first, second, and third tertile of G-Gap: 2.9, 6.2, and 11.0%, respectively; P < 0.001).
G-Gap was similar in those with or without nephropathy (third tertile compared with first or second tertiles of G-Gap: prevalence of nephropathy 38.0 vs. 34.7%; P = 0.548).
The distribution of G-gap status for the whole group varied significantly by HbA1c quintile (χ = 505.8, P < 0.001), noting the striking increase in negative G-gap status in the lowest HbA1c quintile, whereas the positive G-gap prevalence was graded across ascending quintiles (Fig. 1).
The greatest gap between prevalence of drug prescriptions and asthma prevalence was observed in Milan, and it is possible that in this LHU a higher percentage of under-treatment or an over estimation of disease estimated by questionnaire was present [ 31].
However, a wider gap in prevalence between rural and urban areas could be observed in some age groups by 2006.
It is clear that the gap in prevalence of disability between rural and urban areas increased from 1987 to 2006, particularly in the early-retirement years (60 75).
The evidence was provided that a crude increase of 1.50% of disability rates from 1987 to 2006 was mainly due to that the dramatic ageing of population and the gap in prevalence of disability between rural and urban areas has widened, having important practical implications for China.
The gap in prevalence between FT and LLN increased in older age groups.
Our study thus suggested a tremendous gap in prevalence of AERD when compared with other ethnic populations.
