This may occur only infrequently, but even an infrequent difference may have an important impact on a facility's improvement and monitoring efforts.
ABCB1 showed generally low expression and CNAs in 7q21.12 were infrequent; no differences were seen between sensitive and resistant cases, which is in concurrence with others [ 51].
Comparison between replicates showed a nearly 97% correlation while between species showed approximately 93% correlation indicating infrequent hybridization differences as expected with low rates of polymorphism between the two species.
Although frequent words generated larger amplitudes than infrequent ones, these differences didn't reach significance.
However, with a few exceptions, such as the prominent over-representation of GCG|GCG and CCG|CCG, other codon pairs showed infrequent or minor differences in representation.
We obtained a strong frequency effect in the case of weak repetition, frequent words eliciting faster RTs than infrequent ones (mean difference = 77 ms).
As such, the study was underpowered to detect true differences in infrequent outcomes, particularly for mortality at 30 days.
Gender differences were infrequent but men were less likely to provide an analyzable response on the history of hypertension.
Overall boxing was the most infrequent behavior, but sex differences were observed in both same- and mixed-sex pairs (t 95.99) = 3.357, p = 0.0011 and t(136.9) = 2.900, p = 0.0044, respectively) (Fig. 5a).
Although the study was powered to assess the overall patient experience with pH placement and 24 48 hours of testing, the sample size may have been too small to detect significant differences in infrequent secondary outcomes such as failure rates.
29 As useful as these head-to-head studies have been, none has the duration of follow-up or the statistical power to detect differences in infrequent systemic adverse events against the noise inherent in studies conducted in a predominantly elderly population.
