SOX30 and AIDS dementia complex: SOX30 expression was associated with both ADC and SCC patient’s OS by Cox multivariate regression analyses on T/N/M and SOX30 expression, whereas the hazard ratio (HR) was different in ADC (HR < 1.00) and SCC (HR > 1.00) patients (Additional file 1: Table S4), suggesting that SOX30 was a favorable factor for prognosis of ADC patients but was an unfavorable factor for prognosis of SCC patients.
