In multivariate analysis, positive sputum culture at 8-weeks was associated with enrollment in Africa, cavitation on baseline CXR, higher bacillary load on baseline smear and increasing age, but not HIV co-infection.
By multivariate analysis, positive RT-PCR on nasopharyngeal aspirate samples was an independent predictor of death within 30 days.
In the multivariate analysis positive lymph node status was an independent negative prognostic factor (p = 0.001) [ 48].
On multivariate analysis, positive PET/CT findings (for loco-regional and/or systemic recurrence) remained an independent predictor of OS when adjusting for age, histological subtype and initial stage (model 1, Table 5).
Nevertheless, using multivariate analysis, positive fluid balance remained an independent risk factor for 28-day mortality after adjustment for age, gender, diabetes, hypertension, diuretic use, non-renal sequential organ failure assessment (SOFA) and sepsis [ 26].
On multivariate analysis, positive nuclear NF- κB staining (P=0.002), Gleason score (P=0.03) and preoperative PSA serum levels (P=0.02) were independent prognostic factors for biochemical relapse when all the analysed variables were assessed as binarised variables (Table 3).
