We found that most studies included a sufficient number of patients and controls and reported mean PPT values with broad confidence intervals.
Nevertheless, the identification of such complex moderations is often subject to high standard errors and broad confidence intervals (Afshartous and Preston 2011).
Six grams per day oral ganciclovir was most similar in efficacy to IV, although broad confidence intervals prevented a conclusive comparison.
The European clinic studies included 100 person with episodic and chronic migraine, respectively, while the American clinic study included 72 persons with episodic migraine and 128 persons with chronic migraine, providing relative broad confidence intervals for the EDS prevalence, i.e. 14% (8 22%), 20% (13 29%), 32% (25 48%) and 40% (31 49%).
These numbers seem to be more realistic when compared to the observed values in other higher plants, especially considering broad confidence intervals.
In other cases, for example for MAC prophylaxis in Michigan, there were relatively small numbers of patients for whom the clinical service was indicated; this also led to broad confidence intervals and nonsignificant ?2 tests.
There was no evidence of heterogeneity among study centres, except for the association between ED and ΔWCBMI in women (P for heterogeneity = 0.035), driven by a single centre (Doetinchem, the Netherlands) with a small sample size and broad confidence interval, that deviated from the other centres.
Small numbers in some cells resulted in broad confidence intervals.
It showed an especially broad confidence range (3.66; 18.42) [ 54].
20 Given the broad confidence intervals, these results were in agreement with those of our study.
However, limited data are available at the moment, resulting in broad confidence intervals.
