al. 29 (figura 5.7). Dai risultati di questi due studi è<br />
possibile concludere che il trattamento in fase acuta<br />
con VMNI in aggiunta alla terapia medica convenzionale<br />
è in grado di influenzare positivamente<br />
la prognosi dei pazienti sopravvissuti nei mesi successivi<br />
alla dimissione e fino ad almeno 1 anno.<br />
