A pragmatic workflow for handling missing PROM data in registry studies: a methodological scoping review and simulated worked example
Background: Patient-reported outcome measures (PROMs) are increasingly integrated into clinical quality registries. Registry-based PROM data frequently exhibit structural non-response, including patients who never return PROMs (“never-re...

Loss of power by degree of heaping in covariables
Heaping or digit preference is frequently occurring in health research data as well as in deliberate data masking. We investigate the associated loss of power associated by degree of heaping by simulation and illustrate the effect with a...

A finite-sample inferential framework for the weighted kappa coefficient (FWKC) in binary diagnostic agreement studies
Background: The weighted kappa coefficient κ(c), where c is the relative loss of a false-negative result, summarizes beyond-chance agreement between a binary diagnostic test and a reference standard. Established intervals for κ(c) may be...

Sequential randomization tests using e-values for clinical trial monitoring across endpoint types
Background: In randomized trials, repeated interim analyses of accumulating data must keep the Type I error controlled. Sequential analyses that use e-values allow continuous assessment of evidence while controlling their own Type I erro...

Methodological issues relating to case study site selection for a study of emergency department waiting
This paper examines the purposive selection of case study sites in health services and medical research. It describes different data that can inform case selection, and considers some of the challenges encountered when choosing cases for...

Quantifying and adjusting for verification bias in diagnostic test accuracy studies with conditional reference standards
Background: In diagnostic test accuracy studies, it is often infeasible to verify the true disease status of all participants with a gold standard. Several alternative study designs with incomplete verification exist. In a “check the neg...

Initial data analysis of the national German transplantation registry with a focus on kidney transplantation
This study presents an Initial Data Analysis (IDA) of the German Transplantation Registry (TxReg) data for a better data understanding and to inform future data analyses. The IDA is focusing on data on first-time kidney-only transplantat...

Synthesis of comparisons of multiple interventions in infectious diseases research: a scoping review
Background: Evidence synthesis in infectious diseases research often involves comparing multiple interventions to assess relative efficacy or safety, usually through pairwise or network meta-analyses. However, the statistical methods use...
