These data suggest that smaller tumors (<400 mm) are preferred for evaluating therapeutic associated changes in tumor vasculature.
Moreover, one stage methods may be preferred for evaluating treatment-covariate interactions of continuous covariates, incorporating nonlinear relationships, when studies are small, and there is heterogeneity across studies, and particularly for pooling of non randomized trials that may need to be adjusted for several confounders [ 46].
A 50% reduction in plaques (PRNT50 titer) is preferred for evaluating human sera after vaccination because it affords acceptable sensitivity and specificity, although greater reduction in plaque counts (≥ 80%) is useful for epidemiologic studies or diagnostic purposes to avoid or reduce cross-reactivity among flaviviruses in dengue-endemic areas.
While US and MRI also have similar accuracy, CT is preferred because it out-performs US and MRI for evaluating the extra-hepatic abdomen [ 8].
For evaluating the process of teaching, the greatest degree of consensus among educators for actual evaluators was for heads of groups, while they preferred to have self evaluation.
Open ended questions are preferred for studies evaluating overall medicine utilization.
Although echocardiography and MRI are generally preferred for evaluation of cardiac morphology, changes in cardiac morphology (Fig. 20) and the presence of mass lesions (Fig. 21) can be evaluated by cCTA.
As the first step of the statistical analysis, the Mann-Whitney U test for unpaired variables was preferred to evaluate the likelihood of appearance of statistically significant differences in values with relation to sex.
For this reason, 3-D echocardiography (rather than 2-D echocardiography with TDI) would be preferred to evaluate the feasibility of phase analysis on GMPS for the assessment of LV diastolic dyssynchrony.
For electromechanical oscillation estimation, since the length of measured data is limited, some Monte Carlo methods like bootstrap are preferred to evaluate the estimates [24-26] [24-26]
