The phrase "by multivariable analysis" is correct and commonly used in written English.
It is typically used to specify the method or approach used to analyze data or information. You can use it whenever you want to indicate that a certain analysis technique was used to come to a conclusion or make a statement. Example: "The results of the study showed a significant correlation between smoking and lung cancer by multivariable analysis."
These findings were confirmed by multivariable analysis with independent factors (Table 1).
NOSVA was not associated with septic myocardial dysfunction, but with renal failure by multivariable analysis.
All these findings were confirmed by multivariable analysis (data not shown).
By multivariable analysis, independent angiographic predictors of treated segment restenosis included beta or gamma VBT, lesion length, and vessel size.
This score incorporated the three independent mortality risk factors identified by multivariable analysis, each variable of the score being weighted by its odds ratio.
In this subgroup, two prognostic factors were statistically significant for survival: AFP > 400 ng/mL (P = .004) and Spitzer Index (P = .013) as shown by multivariable analysis.
By multivariable analysis with mortality as the outcome variable, admission after day-3 tended to be associated with mortality but did not reach significance when adjusted on patient's characteristics and processes of care.
Among all recorded factors, only renal failure (as assessed by renal SOFA score at day 1) was associated with NOSVA and this difference persisted by multivariable analysis (odds ratio of 1.29, 95%% CI 1.03 1.62, p = 0.03).
Altered afterload (as assessed by lower values of left ventricle end-systolic wall stress) was significantly associated with in-ICU mortality by multivariable analysis, along with fluid balance and SOFA score.
The relationship between TBDs seroprevalence and the risk factors was assessed by multivariable analysis using standard logistic regression models and mixed models using the farm as a random effect.
By multivariable analysis, SAPS II at admission >43 [OR 2.81 (1.16–6.79)] and colonization with Enterobacter sp. or K. pneumoniae species [OR 10.96 (2.93 41.0)] were independent predictive factors for ESBL-PE pneumonia in colonized patients, whereas receipt of >2 days of amoxicillin/clavulanic acid during the ICU stay [OR 0.24 (0.08–0.71)] was protective.
