what p value is stat sig
less than 0.05
formula for relative risk
it happened to in exp group/total in that group all divided by the same in the control/placebo group
formula for RRR
1-RR
formula for absolute risk reduction
arithmetic difference between event rates in groups ie control group event rate - exp group event rate. *if increased risk, this is the ARI (NNH is calculated from this)
formula for NNT
100/ARR. NNH is same but use ARI (absolute risk increase)
what is the NNH
number of patients who would have to be treated for one person to experience an adverse event
what is the NNT
number of patients who would have to be treated with the intervention for one to benefit
what does confidence interval indicate
precision of estimate- confidence that x% of the values overlap with the true value. Wide CI mean less precise
what does a smaller p value mean
less likely result is due to chance
