SCFE slipped capital femoral epiphysis, M male, F female
To determine the size of the population at risk over the entire study period 1998– 2010, we considered all children aged between 5 and 19 years in that period. First, we considered different age-cohorts (one cohort for each age 5, 6,...19 years) that were at risk for developing SCFE in 1998. The follow-up period for each age-cohort was defined from 1998 onwards either up to the year the patient turned 19 years old or until 2010, whichever came first. We also considered different entry-cohorts (one cohort for each year from 1999, 2000,...2010) that consisted of children who turned 5 years old in that year. For each entry-cohort, the follow-up period was
