Although our data do not establish the basis for this correlation, it is instructive to consider one example of a common cause model: greater levels of male sperm may be a common cause that promotes higher levels of early and late progeny production.
For example, Apobec1−/− mice have greater levels of ApoB100 compared with the edited isoform, ApoB48 (Nakamuta et al. 1996) and transgenic rescue of Apobec1in Apobec1−/− animals has been shown to directly alter chylomicron production (Blanc et al. 2012).
For example, recent research has found quitting leads to greater levels of being physically active, greater levels of daily consumption of fruits and vegetables, and to reverse cognitive decline in middle age male smokers.
Greater levels of patient-centered communication, for example, are associated with lower diagnostic testing costs and with more efficient and effective medical visits (Epstein et al 2005).
For example, within the MIKC MADS-box gene family, phylogenies uncover greater levels of overlap among our EST sets than were inferred from simple BLAST-based analyses.
Model I shows a significant association between greater levels of pain and greater levels of depression.
For example, in a study of adolescents attending a public STI clinic in Chicago, greater levels of knowledge were associated with delayed care-seeking among females [ 7].
For example, the evolution of eHealth and mHealth, new forms of communication technology, have led to greater levels of interpersonal connectivity [ 16- 18].
The examples suggest a greater level of utilisation and final outcomes in terms of health, health equity and social and economic gain than is often assumed, whilst still showing much underutilisation.
Yet, Doyle et al. (2001) illustrated an empirical example in which a greater level of genetic diversity was recovered (and thus retained) within a small captive population generated from related founders, characteristics likely of many captive breeding programs (Utter 1998; Hedrick et al. 2000a, b, c; O'Reilly and Doyle 2007).
