Direction of Bias From Nondifferential Misclassification

In this post, I simulate 3 scenarios of non-differential classifications of exposure as demonstrated in Yland et al., 2022: Specificity of exposure 90% and sensitivity 60% Specificity of exposure 90% and sensitivity 70% Specificity of exposure 90% and sensitivity 80% Each of these scenarios will be simulated in 10 thousand datasets of varying sizes: n=100, n=1000, n=10000.

Competing events survival analyses

This is an account of R code by Paloma Rojas-Saunero, PhD available here, which I “translated” to tidyverse code and added some clarifications and figures. This is a longer read, but, hopefully, also is easier to follow for those who use tidyverse.

Using `WeightIt` R package for causal inference analyses

I recently discovered WeightIt R package and was very happy with its functionality and performance. I “delegated” my code computing IPTW to WeightIt and it was faster while producing the same results, as expected.

Antibiotics utilization in Denmark: using R to solve practical tasks in epidemiology

Intro This is a blog post-chaperon for the R-Ladies meet-up Abuja. We are talking R in epidemiology, practical aspects of being R-user and going through data-supported example of how to use R for data aggregation and visualization.

Prenatal exposure to pregabalin, birth outcomes and neurodevelopment – a population‑based cohort study in four Nordic countries

Prenatal pregabalin exposure compared with no exposure showed a 1.1-fold association (95% CI 0.98–1.32) with the prevalence of any major congenital malformation among live and stillborn offspring, and a 1.7-fold association (95% CI 1.02–2.91) with stillbirth; the association was attenuated in Mantel–Haenszel meta-analysis for the latter outcome. We found no association between prenatal pregabalin exposure and risks of birth outcomes other than major congenital malformations or stillbirth. Prenatal exposure to pregabalin compared with no exposure to pregabalin and active comparators showed a 1.3-fold association (95% CI 1.03–1.63) with attention deficit/hyperactivity disorder; the association was attenuated in the analyses using active comparators and Mantel–Haenszel meta-analysis. There was no evidence of an association with other examined neurodevelopmental postnatal outcomes.

Risk of Major Cardiovascular and Cerebrovascular Events in Users of Lisdexamfetamine and Other Medications for Attention-Deficit Hyperactivity Disorder in Denmark and Sweden - A Population-Based Cohort Study

To our knowledge, this is the first population-based observational study using routinely collected administrative data from clinical practice to investigate the cardiovascular and cerebrovascular risk associated with exposure to LDX. Results of the current study suggest that there is little to no increased risk of cardiovascular and cerebrovascular events among patients treated with LDX compared with patients previously treated with other ADHD medications.
