Reflecting the multilevel and integrated features of human health development that are at the centre of life course health-development (LCHD) principles, study designs seek better understanding of social, familial, and genetic contributions to the aetiology of health conditions, exploring the timing ...
Many different study designs can advance a life course health-development framework. In this chapter we review common epidemiologic study designs including (i) cohort studies (general prospective cohort studies, perinatal/birth cohorts, twin studies, and high-risk cohort studies); (ii) case–control...

However, no obvious gap between the two study designs was found in the linear dose-response analyses. In general, case-control studies are more susceptible to recall and selection bias. And population-based case-control studies are generally less prone to selection bias than hospital-based case-...

It may surprise many scientists to discover that interpreting a study result from its P value alone is spurious in all but the most highly powered designs. The reason for this is that unless statistical power is very high, the P value exhibits wide sample-to sample variability and thus does...
Studies of risk factors for MDR-GNB infec- tions and/or colonization are difficult to compare since the study designs, populations, local-epidemiology, and definitions of resistance vary widely [35]. However, some investigations point to similar observations as those de- scribed here [36–38]....
Study type For COPD, there is marked variation (p < 0.001), with RRs higher for prospective studies than for other study designs. For CB, no variation is evident, most RRs coming from cross-sectional studies. For emphysema, where no results come from case-control studies, RRs are again ...
Note that the last three study designs, where exposure was determined before diagnosis, are combined into one category in Table 3 (and the text below based on it). The other 20 studies are classified as subsidiary. Of the principal studies, 262 provide data for all lung cancer, 84 for ...
Though there is a lack of substantive evidence for soccer specifically, early sport specialization has been found to be associated with a greater risk for overuse injuries across multiple youth sports [9]. One study showed that female soccer players 12–15 years of age playing on more than ...
