Adjusting data allows CF Canada to properly compare data between clinics. The lung and nutritional data are adjusted for patient age, sex, age at diagnosis, and pancreatic enzyme status. Without adjusting the data, you would be making unfair comparisons between clinics. For example, we know that lung function worsens as individuals get older. If clinic A has, on average, younger patients than clinic B, and clinic A has a higher average lung function value, this may simply be due to the fact that the patients are younger at clinic A. It would be unfair to say that clinic A is “better” than clinic B if the reason for the higher lung function is simply the younger age of the patient population. By adjusting for factors such as age, we can take into account factors that would have an impact on specific outcomes.
