the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...

Many clinical trials restrict randomisation using stratified blocks or minimisation to balance prognostic factors across treatment groups. It is widely acknowledged in the statistical literature that the subsequent analysis should reflect the design of the study, and any stratification or minimisation variables should be adjusted for in the analysis. However, a review of recent general medical ...

In recent years, a number of infrastructures have been proposed for the collection and distribution of medical data for research purposes. The design of such infrastructures is challenging: on the one hand, they should link patient data collected from different hospitals; on the other hand, they can only use anonymised data because of privacy regulations. In addition, they should allow data dep...

When reasoning about an incompletely known narrative of events, it’s necessary to employ event occurrence minimisation in order to get the expected results from standard temporal projection techniques. However, a blanket default assumption that the known event occurrences are the only event occurrences is rarely legitimate. A finer grain of minimisation is required, which takes into account the...

OBJECTIVE Establishing an association between high chronic stress levels and variables considered to be negative regarding the stress profile for Mexican migrants living in Edmonton, Canada. METHODS A simple random technique was used for choosing the target population; the sample size involved 58 migrants. The Nowack Stress Profile and Maslach Burnout Inventory were used to identify immigrant...
