For animal i in disease state X, a value T X(i) is defined, describing the expected time that animal i spends in category X given progression to X at a previous time step.
These courses don't give progression because the qualifications just aren't good enough," she said.
Each GEE model estimated three regression coefficients related to the association between a given biomarker and progression of the damage score representing the effects of, respectively, the biomarker value at year 1, the time since year 1, and the biomarker-by-time interaction.
One of his guiding lights is a treatise published in 1553 by Diego Ortiz, a composer-performer from Toledo, which shows the novice gambist how to embroider a given melody or chord progression with ornaments, variations, and outright inventions.
Furthermore, C2C levels measured at a given year predicted radiographic progression during the subsequent year.
Multiple regression analysis was applied to determine the predictive value of a given parameter for the progression of renal failure (final serum creatinine).
In addition to the long-term predictive value of the biomarker levels measured at year 1, we also focused on the putative association between a biomarker value observed at a given visit and the progression during the subsequent year.
Progression-free rate was the proportion of patients without progression at a given time.
The bottom line is that although a "step-by-step approach," "from the safest to the riskiest," is prudent, a good history and clinical judgment are required to ascertain what, exactly, would constitute such a progression for a given patient.
