This behaviour should also be monitored to reach an accurate estimation of the prevalence of 'over-persistence' and to obtain a better understanding of why couples are not able to follow recommendations to stop treatment.
The modelling study described here proposes an estimation of the budget impact of non-persistence with bisphosphonates, by assessing cost-effectiveness of "ideal persistence" compared to current persistence in real-world and estimating the annual total cost of non-persistence for France.
Figure 3 presents the Kaplan-Meier estimation of persistence (time to discontinuation) for the NNRTI and PI cohorts.
It is shown that using established approximate relations for the estimation of persistence length for semi-flexible macromolecules leads to differences between different methods or even to a modified behavior, especially at high chain stiffness.
When extrapolated, this result allowed an estimation of the global cost of non-persistence in France to €30.5 million per year.
Macias-Fauria, M., Grinsted, A., Helama, S. & Holopainen, J. Persistence matters: Estimation of the statistical significance of paleoclimatic reconstruction statistics from autocorrelated time series.
This method allows a separation of the domains of population persistence versus those of extinction and enables the identification of populations on the brink of extinction as it allows the estimation of the minimum population size required for population persistence.
As participants are generally better motivated and under close medical supervision compared with those receiving therapy outside the clinical trial setting, these rates do not necessarily reflect real-world use and from this point of view, the RAMQ database allows a more accurate estimation of adherence and persistence.
Finally, since it has been observed that the sum of the persistence parameters exceeds the unitary value in earlier GARCH estimations, it can be deduced that the variance might not be well behaved in such models.
This introduces the important issue of the persistence of GWEBV predictions over generations in the absence of marker effects re-estimation, and few studies have examined this issue, e.g. [ 11].
