As it can be seen in Table 2, another proportion of casualties recorded as 'serious' by the police, actually had an MAIS equal to 1 or 2, corresponding to another type of mis-reporting, that of overestimating injury severity [16].
When surgical intervention in one group is compared with a non-surgical treatment in another, the proportions of patients lost to follow up could be expected to differ between the groups.
If the exposures are acting in a similar manner and can be substituted for one another in proportion to their potencies, the concentration addition (CA) model is used as null model.
This idea then led Newton to the even more revolutionary view in proposition seven of Book III that all bodies gravitate toward one another in proportion to their quantity of matter.
CA assumes that one agent can be substituted for another in proportion to their relative potencies; it is usually thought to apply to agents that work by similar mechanisms and is not limited to linear dose response curves (Kortenkamp 2007).
Because this derivation assumes that exposures A and B can be substituted for one another in proportion to their potencies, CA is usually considered appropriate for agents that act via a "similar" mechanism (U.S. EPA 2000), although there has been considerable discussion as to the meaning of "similar" (Borgert et al. 2004).
The hospitals were different from one another in the proportion of patients with an indicator of infection (p<0.0001), after controlling for health plan, patient age, and patient sex.
After having accounted for this section-based difference in soldier proportion, another significant section-based difference in the proportion of adult sexuparae (winged migrants from gall) was found to persist.
In another word, the proportion of non-coding DNA increases with genome size faster in eukaryotes than in non-eukaryotes.
The proportion of eligible persons prescribed PCP prophylaxis in a large U.S. cohort of HIV-positive persons was 80% [9], whereas in another study, the proportion of providers who adhered with guidelines for prescribing PCP prophylaxis in federally funded HIV treatment facilities ranged from 80 94% [10].
