请问各位老师,下图是想表明什么呢?谢谢老师!
原文中,只有一处提及该图:
原文:Decision Curve Analysis: The decision curve analysis of the VISAGE score provides
better net benefit than the alternate options (Supplemental Digital Content 9)
Legend:Decision curve analysis was performed to evaluatethe net benefit ofdecision for extubation using the VISAGE score. Threshold probability is the probability ofextubation success from which a clinician considers that it may extubate. Thehighest curve at any given threshold probability is the optimal decision-makingstrategy to maximize net benefit. Across the range of reasonable thresholdprobabilities (probability of extubation success greater than 50%), net benefitwas maximized by the VISAGE score approach compared to alternative strategy(extubate all or extubate none).
