Across several different data structures and dropout mechanisms, tests of significance for difference in means of slope coefficients fitted to LOCF data maintained appropriate Type 1 error protection.
The procedure is useful, because responder rates can be understood more intuitively than a difference in means of rating scales.
We test for differential expression using a Welch's t-test for a difference in means of samples with unequal variances, and use the sum of the negative log P values across the nine cohorts as a single summary statistic per gene.
The proportion of internal trainers is sharply higher among treated workers than among non-treated ones (53.8 and 37.3% respectively, i.e. a difference in means of 16.5% points).
Comparative descriptive and inferential statistical analyses of pastoral and peri-urban camel systems were done to test for any statistically significant difference in means of the test parameters.
A greater mesial movement of the U6 was detected in the two-step/conventional anchorage group with a std difference in means of − 2.55 mm (95% CI − 2.99 to − 2.11) between the two methods.
A greater distal movement of the UI was detected in the en masse/miniscrew group with a standardized (std) difference in means of − 0.38 mm (95% CI − 0.70 to − 0.06) between the two groups.
Of interest in the peri-operative group are the major differences in energy at yield and yield strain with difference in means of 30%% (energy at yield) and 29%% (yield strain) and appropriate statistical power.
The balancing test on the other hand, performs a balancing t-test of difference in means of the specified covariates between the control and treated groups during the pre-regulation period [32].
For instance, for the case in Fig. 2B we draw surrogate "Loss" and "Not Win" samples with 9 and 14 data points, respectively, and then determine the difference in means of the two surrogate samples.
Statistical analysis of these results showed a significant difference in means of rmsd values (student's t-test with equal or unequal variance as appropriate, p-value<0.02) calculated for all complexes from the groups –MultiProteins∶DNA, -SingleProtein∶DNA and –SingleSameProtein∶DNA calculated after fitting each DNA structure onto the corresponding canonical A-DNA and B-DNA structures (Table 2).
