The Audit Commission methodology incorporates however the attrition of theatre time brought about by cancelled operating lists and national estimates suggest that these comprise approximately 10% of all planned Trust sessions [ 23].
For their part, Toronto brought on Johnson and Benoit Cheyrou for Osorio and Cooper, as Vanney anticipated the attrition of extra-time, and possibly another decisive interception from Cheyrou, who had scored the winner against Montreal after just 92 seconds on the field.
Limitations include the contextual appropriateness of the resilience measuring instrument, differential attrition and selection of time points.
The potential for such research collaborations to maximise the benefits of cohort studies (e.g., identification of causal risk factors, retest effects, assessment of developmental trajectories), while minimising the negatives (e.g., cohort effects, participant fatigue, attrition, cost, length of time) [ 14] are clearly advantageous.
Attrition of telomeres over time is a characteristic feature of aging and serves as one of the major markers for premature aging [11].
A longitudinal study may see the attrition of participants over time.
The development (or attrition) of routines over time reflects the more general tension between continuity and change in organisational life [ 10].
The numerator for the rate was number of cases of attrition, while the denominator was the total of time to attrition plus time on study (see Fig. 1), expressed in 100 person years.
Lastly, though our study suggests that asynchronous and didactic education may not be equivalent for knowledge acquisition, we did see similar knowledge attrition after a period of time in both groups so that we cannot favor one method over the other in terms of retention of knowledge.
Power analysis (G-power) is based on a 3-month effect size of 1.0 taking into account a maximum of 20% attrition over time and loss of power due to multiple imputation.
