Abbreviations: TLs Temporal lobes, TLI Temporal lobe injury, CI Confidence interval, TLV Volume of an individual temporal lobe, Dmean Mean dose to temporal lobe, Dmax Maximum dose to temporal lobe.
*D0.1CC is the dose to 0.1 ml of the temporal lobe volume; other absolute volumes are indicated in a similar manner.
§D1 is the dose to 1% of the temporal lobe volume; Other percentage volumes are indicated in a similar manner.
♀V10 is the absolute volume of the temporal lobe that received more than 10 Gy; other doses are indicated in a similar manner.
