Percent change in age- and sex-adjusted standard prevalence rate (SPR)^a ratio for dialysis patients per 10-min increase in travel time to the nearest dialysis facility (census block <i>n</i> = 1,867).

CI: 95% confidence interval. aSPR means that prevalence rate of dialysis patients in each census block was adjusted by using the distribution of the age and sex of the census block. bA significance of interaction (P<0.05) between travel time and land type means that there is a synergetic association between these two variables. cAdjusted for rate of tertiary industry workers in census block, population density, and geographic type (mainland or island).CI：95%置信区间（confidence interval）。 aSPR 指依据各普查区块的年龄与性别分布，对该区块内透析患者的患病率进行校正后的患病率。 b 出行时长与土地类型之间的交互作用具有统计学显著性（P<0.05），表明这两个变量之间存在协同关联。 c 校正因素包括普查区块内第三产业从业者占比、人口密度以及地理类型（大陆或岛屿）。
