Sir,
The World Federation of Neurosurgical Societies (WFNS) scale for grading patients with aneurysmal subarachnoid hemorrhage (SAH) was originally published in 1988,[
Figure 2
Mean GOS scores at discharge showing that in the m-WFNS scale, there was significant difference between any neighboring grades (a). By contrast, in the o-WFNS scale, the significant difference was observed only between grade I/II and between grade IV/V patients (b).

Figure 3
The results of receiver operating characteristic curve analysis showing that the m-WFNS scale had significantly higher area under the curve values (i.e. better outcome predictability) than the o-WFNS scale by mRS.
