What they need is explicit targeting with a customised package of services based on their illness profile, at a time and place convenient to them with minimum or no cost implications. Epidemiological research on the association between diesel exhaust exposure and lung cancer risk has some methodological challenges that give rise to different conclusions and intense debates. This raises the question about the role of selective citation and of citation bias in particular. Our aim was to investigate the occurrence and prevalence of selective citation in this field. Citation analysis. Web of Science Core Collection. We identified 96 publications in this network, with 4317 potential citations. For each publication, we extracted characteristics such as study conclusion and funding source. Some of these characteristics are related to the study content study design, sample size, method of diesel exposure assessment, type of diesel technology under investigation, and whether smoking had been adjusted for. Whether a citation occurs or not, measured and analysed according to the preregistered protocol. Exploratively we analysed the association between funding source and study conclusion. but the evidence for citation bias was weak. It seems that factors related to the methodology had more impact on citation than the conclusion of a study. Interestingly, publications that were funded by industry were more skeptical about a causal relationship between diesel exhaust and lung cancer compared to non-profit-funded publications. We aim to describe the social network members of participants of a behavioural intervention, and examine how the effects of the intervention may spillover among network members. Secondary analysis of a step-wedge randomised controlled trial. Change agents (CAs) were recruited from waiting rooms of HIV treatment faciliti
