In multivariate analysis, five factors, which were present prior to the exposure to placebo, were found to be associated with placebo response.
In multivariate analysis, five variables were first included in the model: antibiotic therapy, intracranial catheter, brachial catheter, intramuscular injections and care rooms used.
Using multivariate analysis, five variables were identified which were associated with adverse outcomes: age >65, hemoglobin ⩽11.5, platelet ⩽100 000/microliter, β2 microglobulin >3 mg/l and serum monoclonal protein concentration >70 g/l.
In the multivariate analysis, five variables were significantly associated with mortality: inappropriate initial treatment in the emergency room, hypercapnia, low estimated clearance of creatinine, elevated NT-proBNP or BNP, and clinical signs of ventilatory failure (6).
However, a recent German, multicenter, retrospective review documented, in a multivariate analysis, five negative prognostic factors, including performance status, platinum-sentive disease, tumor grading, FIGO staging, and presence of multiple vs single lesions.
In a multivariate analysis, five risk factors were identified and associated with VTE risk in surgical cancer patients: age above 60 years, previous VTE, advanced disease, anaesthesia administered longer than 2 h and bed rest longer than 3 days (Agnelli et al, 2006).
By multivariate analysis, two factors were independently associated with a significantly decreased risk of ≥20 % MAP drops during changeovers, namely, SIP (odds ratio, 0.47; 95 % confidence interval, 0.22 0.98) and norepinephrine dosage >0.5 μg/kg/min (odds ratio, 0.39; 95 % confidence interval, 0.19 0.81).
For multivariate analysis, two logistic regressions were computed with PSA values, one with PSAt and one with PSArel because of their collinearity, as well as with PSA doubling time, PSA velocity, and D'Amico risk group.
Considering multivariate analysis, two factors maintained independent association: dedicated ultrasound machine availability (RR = 2.20 [1.26–3.29], p =0.005) and proportion of POCUS-trained intensivists (RR = 1.91 [1.32 - 2.77], p = 0.001) (Additional file 2: Table S1).
Since the OR associated with illiteracy was little modified by control for at risk exposures in multivariate analysis, one may assume that important risk practices associated with low education were not measured in this study.
In the multivariate analysis, three models will be used.
