Two additional measures idea density (defined as the total number of semantic units divided by total number of words in a speech sample) and efficiency (the total number of semantic units divided by duration of the speech sample in seconds)—were also computed (Ahmed et al., 2013).
State duration of sample storage before testing.
Duration of sample harvesting was less than 15 min.
The linear trends in the means, percentages, or prevalences by duration of diagnosed diabetes in the total sample or differences in prevalences by type of diabetes and current insulin use among men and women with type 2 diabetes were tested by using orthogonal polynomial contrasts.
Figure 6A shows the mean ANA titers for the Libby samples when subgrouped by duration of exposure and demonstrates that the titers were significantly higher for those subjects exposed to asbestos for > 5 years.
The sample size for this analysis was small so there was limited power to investigate effects by duration of ART.
In our study, however, as well as in that by Mathelin et al. [ 2], storage duration of samples did not differ between cases and controls and still in both studies a decrease was found in cases compared to controls.
Total duration of sampling took roughly three months (from May to July , 2008.
The heterogeneous results were not explained by setting, duration of symptoms, sample size, or method of outcome measurement.
This heterogeneity was not explained by setting, duration of symptoms, sample size, or method of outcome measurement.
