Poor knowledge determined the very low use of universal precautions that can prevent major proportion of exposure to BBPs.
In the intrapair analysis, variance due to shared factors is removed, and a relatively larger proportion of exposure variance is thus due to measurement error.
A distinct and useful pair of indicators with which to interpret the results of the above equations are the proportion of exposure which occur indoors and the proportion that occurs during sleeping hours.
In other studies, given the range of the purpose of biomass fuel use, cooking has been implicated as the main factor for the greater proportion of exposure to IAP in developing countries [ 4, 51].
The proportion of exposure time with relative mortality below 300, 400, 500 and 600% was 28, 43, 61 and 64%, respectively, suggesting that more than 50% of patients (those with lower relative mortality) could be insurable.
Although we lack information on the non-respondents, some of them may not have responded due to a higher proportion of exposure to IPV and poor mental health than respondents.
In our study population (which excluded IDU or those who were hepatitis C positive), the proportion of exposure time with relative mortality below 300, 400, 500 and 600% was 28, 43, 61 and 64%, respectively.
PAF estimates depend on RRs and the proportion of exposure in a given population, which has to be considered when generalizing to other populations where low PA levels could differ.
Because one sees a high proportion of outcome Y in one area of a map of a country, and a high proportion of exposure X in the same area of a second map of the country, one cannot conclude that X causes Y.
We also performed logistic regression using time as a linear variable was performed to assess trends in proportions of exposures and behavior types over the time period between 2002 and 2005.
