Objective: The purpose of the study was to evaluate the outcomes and back to the sport in soccer players with anterior cruciate ligament (ACL) reconstruction during one year. Materials & Methods: 32 soccer players who underwent reconstruction of ACL via BPTBG (Bony-Patellar Tendon-Bony graft) (Technique Modified Clancy) selected and randomly divided into two 16-subject traditional and accele...
High reliability systems generally require individual system components having extremely high reliability over long periods of time. Short product development times require reliability tests to be conducted with severe time constraints. Frequently few or no failures occur during such tests, even with acceleration. Thus, it is difficult to assess reliability with traditional life tests that reco...
Informative drop-out arises in longitudinal studies when the subject's follow-up time depends on the unobserved values of the response variable. We specify a semiparametric linear regression model for the repeatedly measured response variable and an accelerated failure time model for the time to informative drop-out. The error terms from the two models are assumed to have a common, but complete...

Background: Trial data often does not cover a sufficiently long period of time to truly capture time-toevent endpoints, however, Health Technology Assessment (HTA) bodies often require overall survival (OS) and progression-free survival (PFS) estimates. Often, significant survival effects are found beyond the time period observed in clinical trials, thus, extrapolation of trial results is requi...
