Abstract
Background
Some populations targeted in survey research can be hard to reach, either because of lack of contact information, or non-existent databases to inform sampling. Here, we present a methodological "case-report" of the yield of a multi-step survey study assessing views on health c...... hiện toàn bộ
Coding linguistic elements in clinical interactions: a step-by-step guide for analyzing communication formBMC Medical Research Methodology - - 2022

AbstractBackgroundThe quality of communication between healthcare professionals (HCPs) and patients affects health outcomes. Different coding systems have been developed to unravel the interaction. Most schemes consist of predefined categories that quantify the content of communication (thewhat). Though ...... hiện toàn bộ
A comparison of multiple imputation methods for missing data in longitudinal studiesBMC Medical Research Methodology - Tập 18 - Trang 1-16 - 2018

Multiple imputation (MI) is now widely used to handle missing data in longitudinal studies. Several MI techniques have been proposed to impute incomplete longitudinal covariates, including standard fully conditional specification (FCS-Standard) and joint multivariate normal imputation (JM-MVN), which treat repeated measurements as distinct variables, and various extensions based on generalized lin...... hiện toàn bộ
Impact of socioeconomic inequalities on geographic disparities in cancer incidence: comparison of methods for spatial disease mappingBMC Medical Research Methodology - Tập 16 - Trang 1-14 - 2016

The reliability of spatial statistics is often put into question because real spatial variations may not be found, especially in heterogeneous areas. Our objective was to compare empirically different cluster detection methods. We assessed their ability to find spatial clusters of cancer cases and evaluated the impact of the socioeconomic status (e.g., the Townsend index) on cancer incidence. Mora...... hiện toàn bộ
Using linear and natural cubic splines, SITAR, and latent trajectory models to characterise nonlinear longitudinal growth trajectories in cohort studiesBMC Medical Research Methodology - Tập 22 - Trang 1-20 - 2022

Longitudinal data analysis can improve our understanding of the influences on health trajectories across the life-course. There are a variety of statistical models which can be used, and their fitting and interpretation can be complex, particularly where there is a nonlinear trajectory. Our aim was to provide an accessible guide along with applied examples to using four sophisticated modelling pro...... hiện toàn bộ
