In each Poisson model, we defined the variables as age (1: 18-49, 2: 50-59, 3: 60-69, 4: 70-79, and 5: ≥80 y) In each Poisson model, we defined the variables as age (1: 18-49, 2: 50-59, 3: 60-69, 4: 70-79, and 5: ≥80 y), and the ordered code was treated as a continuous variable); year (1-9 for 2000-2008, treated as a continuous variable); season (spring, March-May; summer, June-August; fall, September-November; and winter, December-February, with spring as reference); no diabetes (compared with diabetes); and regulation (0: 2000-2003, 1: 2004-2008).
