IHR = 1 indicated no synergy between variables, IHR <1 expressed a reduction of risk due to variables synergy, while IHR >1 denoted an increased risk.
These patterns range from relatively high, stable vaccine coverage across all cohorts with occasional outbreaks (for relatively low disease risk) to extremely variable vaccine coverage from one cohort to the next with regular outbreaks (for relatively high disease risk).
Additionally, the threshold for assigning high-risk/low-risk status to variable combinations can also be controlled by the user.
In the context of the cotton-top's cooperatively breeding groups, this is postulated as being adaptive for determining the variable risk to one's group members.
T-cell apoptosis was evaluated in children and adolescent 35 females/40 malesubjectsts comprising recent-onset and long-standing T1D subjects and their first-degree relatives, who are at variable risk to develop T1D.
Exclusion criteria, designed to decrease risk to subjects and potential confounding variables, excluded subjects who were acutely ill, pregnant, currently lactating or planning to conceive within 90 days.
Every variable from pressure, temperature, fluid type, and well depth to logistics and metocean conditions requires control; an uncontrolled variable represents risk to the successful outcome of the well test.
Direct paths were measured from the exogenous manifest variable, criminal risk, to the exogenous latent constructs, social support quality and quantity.
They describe that the differences are most likely due to the inherent limitations of retrospective studies that include biases in selection of control and exposure to risk variables.
Next complementary bivariate analyses were performed comparing sociodemographic and risk factor variables to initial commitment to both HIV prevention interventions.
