A goodness‐of‐fit test for regression models with discrete outcomes

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Regression models are often used to analyze discrete outcomes, but classical goodness‐of‐fit tests such as those based on the deviance or Pearson's statistic can be misleading or have little power in this context. To address this issue, we propose a new test, inspired by the work of Czado et al.

Non‐negative Gaussian estimation of variance components in random effects models

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract When used to estimate variance components (VCs), confidence intervals (CIs) can be truncated at zero, have a point estimate not in the quoted CI, be empty with positive probability, or be all‐inclusive. This is because they have conflicting dual roles, since they are considered to cover the parameter with a specified probability while also ...

Patient‐ and Clinician‐Related Factors Associated With the Reduction in Opioid Use Among Adults With Chronic Non‐Cancer Pain: A Systematic Review

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
Despite known risks, opioids are widely used for chronic non‐cancer pain (CNCP). Clinical guidelines now recommend deprescribing, but factors predicting success are poorly understood. This systematic review aimed to identify clinician and patient factors associated with attaining successful opioid dose reduction or discontinuation in adults with CNCP ...

Segmental Hair Analysis of Diphenhydramine and Cyclizine Following a Single Dose

open access: yesDrug Testing and Analysis, EarlyView.
A single oral dose of diphenhydramine and cyclizine can be quantified in human head hair for a minimum of 5 months and, in certain cases, for up to 1 year following intake. Among 12 study participants, the measured concentrations ranged from 0 to 610 pg/mg within 1 year post‐intake.
