1. Among 100 000 patients treated with NSAID X over a given time period, 10 had a renal event.
In the untreated population, one out of 100 000 experienced a renal event over the same period of time.
Calculate the absolute risk in patients who use NSAID X
Calculate the reference risk
Calculate the excess risk and interpret the result
Calculate the relative risk and interpret the result
If 1% of the US population use NSAID X over the period of time, what is the etiological fraction of the risk in the population?
2. There are 50 000 hospital admissions per year in the US. How many could be avoided if NSAID X was withdrawn from the market?
Among one million patients treated with NSAID X for a given period of time, 10 had an agranulocytosis.
In the untreated population, one in a million had an agranulocytosis during the same period of time.
Calculate the absolute risk in patients who use NSAID X
Calculate the reference risk
Calculate the excess risk and interpret the result
Calculate the relative risk and interpret the result
If 1% of the US population use NSAID X over the period of time, what is the etiological fraction of the risk in the population?
There are 4000 hospital admissions per year in the US for agranulocytosis. How many could be avoided if NSAID X was withdrawn from the market?
