Summary statistics for primary analytical sample of 137,014 child‐year observations based on 34,510 unique children (136,937 child‐year observations with gender data and 137,012 child‐year observations with county‐level data including dentist supply and median household income).
*The sum of the rate of any comprehensive exam without treatment within 91 days from the date of the exam and rate of any comprehensive exam with treatment within 91 days exceeds the rate of any comprehensive exam because two comprehensive exams in the same year, one without treatment within 91 days and the other with treatment, are counted only once in the indicator for any comprehensive exam. The summary statistics are rounded to two decimals.
