  • Data stratified by percentile are the percentage of time that practitioners report spending in each activity, averaged across all practitioners in a given percentile ranking of time spent in that activity. Separate percentile ranks were calculated for each activity.

  • a P-values represent a test of a linear time trend that includes all survey years and is based on a 95% confidence interval. Linear regression was used to evaluate continuous variables and a Cochran-Armitage test was used to evaluate linear trends in proportions.

  • b Combined numbers of surveys sent to NKF members and to other APs is unknown.

  • c Skewed response distributions with the following 50th–90th percentile ranges in 2018: peritoneal dialysis 0%–10%; hospital 0%–50%; education 0%–5%; office 15%–65%; research 0%–5%; administrative 0%–10%.

  • d 90th percentile reported 0% time participating in this activity in 2018.
