  1. T transmitter, R recipient
  2. aSequences of T9 are derived from full-length env clones only after several SGA attempts failed
  3. b Early antiretroviral treatment (eART) was started immediately after infection and HIV-1 was transmitted upon virus rebound after structured treatment interruption (STI)
