Hazard ratios differ from relative risks and odds ratios in that RRs and ORs are cumulative over an entire study, using a defined endpoint, while HRs represent instantaneous risk over the study time period, or some subset thereof. Hazard ratios suffer somewhat less from selection bias with respect to the endpoints chosen and can indicate risks that happen before the endpoint.

are hazard ratio and relative risk the same?

A: no

The reciprocal of a fraction is another fraction with the numerator and denominator exchanged. The reciprocal of 3 7 (\displaystyle ( frac (3)(7))) , for instance, is 7 3 (\displaystyle ( frac (7)(3))) . The product of a fraction and its reciprocal is 1, hence the reciprocal is the multiplicative inverse of a fraction. The reciprocal of a proper fraction is improper, and the reciprocal of an improper fraction not equal to 1, that is, numerator and denominator are not equal, is a proper fraction.

will the reciprocal of a proper fraction be a proper fraction?

A:
no
