Fig 3. Minimum control event rate (CERmin) for preeclampsia with varying quality-adjusted life years (QALYs) gained, at a fixed treatment event rate (TER) for preeclampsia of 6.0%.

Fig 3

CERmin calculated as: TER + [DC / (QALYs gained x $50 000)], assuming a direct cost (DC) of ASA of $10 per pregnancy. The dashed blue lines indicate that at 0.52 QALYs gained [1], the CERmin for preeclampsia is close to the TER (6.0%). At a more modest gain of 0.05 QALYs, the CERmin increases slightly to 6.4% (dashed red lines).
