Spørsmål #29

A certain clinical study shows treatment 1 to be better to reduce the mortality (number of deaths) than treatment 2 for a certain disease with a p value (significance) of 5%. What does this mean?

The probability of dying of the disease with treatment 1 is 5% lower than with treatment 2

The number needed to treat the disease with treatment 1 instead of treatment 2, in order to reduce the number of deaths by one patient, is 5

The difference may be real, with a probability of 95%

The difference may be real, but only with a probability of 5%
