However, the discovery of a viral implication in CNS tumorigenesis may open different ways for preventing tumours with a constant fatal outcome such as glioblastomas.
DOI: http://dx.doi.org/10.7554/eLife.04785.002 An important question for evolutionary biology is how developmental processes can compensate for variable environmental, signalling, or regulatory inputs to create a constant phenotypic outcome (Waddington, 1942).
Therefore, while all other variables in the model are held constant, the outcome variable changes by 100 times the exponential function of the model parameter estimate as a percentage for a 1-unit increase in a continuous independent variable.
They reported a low negative correlation between tear size and scores of the SST and Constant-Murley outcomes in both sexes (women: -0.35 and -0.35; men: -0.43 and -0.49 respectively) and a negative correlation between subjective scores and age in women but not in men.
In addition, facility was included as a control variable in order to hold constant the effect (on the outcomes) of any unmeasured systematic differences in the characteristics of the six clinical populations or in the quality of care provided in the six settings.
The results of this investigation suggest that, if the assumption of non-differential misclassification and constant prevalence of outcome is correct, the relative risks for health outcomes may be becoming slightly more biased towards the null with each contact.
Ferran et al. [34] compared Rockwood pin fixation (17 cases) and low contact dynamic compression plate (LCDCP; 15 cases) in displaced midshaft clavicle fractures and found no significant difference after 12 months in functional outcome (Constant score p = 0.37).
Confidence intervals of the SRM are calculated assuming the change score is normally distributed [ 39], and the SD of the change is treated as constant for each outcome.
To calculate the sample size we used the primary outcome Constant Shoulder Score with a range from zero to 100 points.
Furthermore, most methods assume approximate normal distributions of the residuals from an applied model where the standard deviation is constant over the outcome space.
