The sample size calculation is based on three commonly used mediation tests: Sobel's method, distribution of product method and the bootstrap method. Among the three methods of testing the mediation effects, Sobel's method required the largest sample size to achieve 80% power. Bootstrapping and...
One-touch handling of blood samples for analysis is a reality with Tempus1800®. The samples are sent in the ordinary sample tubes with no packing and unpacking – this means that the person taking the blood sample is the only person touching it until it, is analysed at the lab. ...

These factors, together with our moderate sample size, might have reduced our chances of detecting genetic effects that are sensitive to reading experience. Nevertheless, we did observe one suggestive finding in our longitudinal analysis: an interaction of rs759178, NWRF, and educational time-point....
Full size image The multiple correspondence analysis extracted two factors, which we will name (1) “perversity–psychological maladjustment” and (2) “lack of confidence and faith–depathologization” to help with interpretation. Factor 1 (vertical; “perversity–psychological maladjustment”) explains...
To investigate the associations between residential green space and mental health among people living alone via the potential serial mediation of green space visits and social restoration processes (RQ1) and to compare these processes to respondents living with a partner (RQ2), we specified a multi...

power analysisWhen planning mediation studies, researchers are often interested in the sample size needed to achieve adequate power for testing mediation. Power depends on population effect sizes, which are unknown in practice. In conventional power analysis, effect size estimates, however, are often ...

Sensitivity analysisTreatment‐by‐mediator interactionThis study provides a template for multisite causal mediation analysis using a comprehensive weighting‐based analytic procedure that enhances external and internal validity. The template incorporates a sample weight to adjust for complex sample and survey...
