As a consequence of the COVID-19 pandemic, the number of decentralized clinical trials, trials conducted in whole or in part at locations other than traditional clinical trial sites, significantly increased. While these trials have the potential advantage of access, participant centricity, convenience, lower costs, and efficiency, they also raise a number of important ethical and practical concerns. Here we focus on a number of those concerns, including participant safety, privacy and confidentiality, remote consent, digital access and proficiency, and trial oversight. (...) Awareness of these ethical complexities will help foster the development of processes and cooperative solutions to promote safe, ethical trials going forward, optimized to decrease burden and increase access for all participants.

This commentary analyses the quantitative parameters of Reichle et al.'s model, using estimates when explicit information is not provided. The analysis highlights certain features that appear to be necessary to make the model work and ends by noting a possible problem concerning the variability associated with oculomotor programming.

This commentary focuses on two aspects of eye movement behaviour that E-Z Reader 7 currently makes no attempt to explain: the influence of higher order psycholinguistic processes on fixation durations, and orthographic influences on initial and refixation locations on words. From our understanding of the current version of the model, it is not clear how it may be readily modified to account for existing empirical data.
