In the multivariate model, advanced age (Odds ratio per 10-year increments 1.22, 95%CI 1.02 1.45), a positive blood culture (Odds ratio 2.46, 95%CI 1.17 5.14), and a low thrombocyte count on admission (Odds ratio per 100,000/mm3 increments 0.67, 95%CI 0.47 0.97) were significantly associated with a CSF WBC <1000/mm.
In multivariate modeling, advanced age, elevated right atrial pressure, elevated serum creatinine, and worsened functional class significantly predicted shorter survival (P =.01, P =.01, P =.01, P <.01), whereas vasodilator response predicted improved survival (P =.01).
In the multivariate Cox-regression model, advanced age and high-5FU clearance proved to be unfavourable prognostic factors for both DFS and OS.
On admission, characteristics associated with spontaneous gram-negative bacilli meningitis by multivariate modeling were advanced age, history of cancer, nosocomial acquisition of infection, urinary tract infection as distant focus of infection, absence of rash, hypotension, and a high cerebrospinal fluid white-cell count.
A multivariate model was developed in the derivation cohort using an exhaustive modeling approach.
Variables exhibiting association with outcomes at a bi-variate risk ratio (RR) of ≥1.5 or ≤0.60 or at a p-value of <0.10 were advanced into multivariate models to control for confounding and to estimate the independent impact of each factor on PTLC.
A multivariate model of early reading acquisition.
However, in our study, the deleterious effect of blood pressure disappeared in the multivariate model.
The impact of malnutrition on morbidity, mortality, length of hospital stay and costs evaluated through a multivariate model analysis.
Pleural invasion and tumor grade were not significant in this multivariate model, after controlling for other variables.
It is a multivariate model.
