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