Furthermore, survival estimates for infrequent combinations of risk factors are not reliable and therefore provide little information on the prognosis of patients with these risk factors.
As such, the posterior LOT is sensitive to 'low-level' linguistic stimuli (unfamiliar characters or infrequent letter-combinations), while activation becomes hierarchically more anterior for frequent letters, bigrams, quadrigrams, and the most anterior – for words [20].
By making use of frequent itemset mining, we could filter out all the infrequent drug combinations to achieve the following two goals: 1) a greatly reduced computational time, and 2) a reliably estimated OR, given sufficient support, enabling nonzero or large enough cell sizes in the corresponding contingency tables for calculating the OR.
Common G/P combinations, infrequent patterns, and mixed-infection combinations were all detected (Table 4).
Lisle said the problem stems from a combination of infrequent technological glitches and errors entered by people using the system.
"The complaint was a common one for women of the era," writes A'Lelia Bundles, her great-great-granddaughter, "due usually to a combination of infrequent washing, illness, high fever, scalp disease, low-protein diets and damaging hair treatments".
The combination of infrequent fliers and the Transportation Security Administration's new initiative that allows randomly selected passengers to receive expedited screening — an initiative that will continue during the holidays — has the potential to create passenger pileup.
Insensitive measurements of adherence in our clinic (self-report and pill counts) in combination with infrequent viral load testing made it difficult to exclude this possibility.
It is noteworthy that there is no significant LD among these 4 SNPs, but this haplotype combination, though infrequent in the population, was a useful indicator of cancer risk.
