Relative Risk
95, 95, no
Confidence interval of 95%; values are -.07 & 3.7; this means that ___% of the time the value will lie between -0.7 & 3.7. There is a __% chance there could be a one. So there is ___ relative risk
95, 5, significant
Confidence interval of 95%; values are 2.3 & 3.6; this means that ___% of the time the value will lie between 2.3 & 3.6. There is only a __% chance there could be a one. So there is a __ relative risk
Yes, one does not fall in that interval
Does a confidence interval of 95% between 2.3 & 3.6 indicate there is a significant risk? Why?
independent
Equal to 1.0 = exposed and unexposed groups have the same risk of developing the disease; exposure and disease appear to be ____
a
Exposed and unexposed groups have the same risk of developing the disease a) Equal to 1.0 b) Greater than 1.0 c) Less than 1.0
b
Exposed subjects have a greater risk of the disease a) Equal to 1.0 b) Greater than 1.0 c) Less than 1.0
a
Exposure and disease appear to be independent a) Equal to 1.0 b) Greater than 1.0 c) Less than 1.0
c
Exposure appears to protect against the disease a) Equal to 1.0 b) Greater than 1.0 c) Less than 1.0
b
Exposure is associated with the disease a) Equal to 1.0 b) Greater than 1.0 c) Less than 1.0
greater
Greater than 1.0 = exposed subjects have a ____ risk of the disease; exposure is associated with the disease
3
