Work out qrisk estimate instantly with clear inputs, formula shown and shareable results.
Interprets a QRISK 10-year cardiovascular risk percentage against the NICE 10% treatment threshold and converts it into events per 100 people and a number needed to treat.
Threshold and NNT
Gap = QRISK% - 10; absolute benefit = QRISK% x relative risk reduction / 100; NNT = 100 / absolute benefit
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
