The estimate of 6.9% attributable mortality, however, was determined through chart review, not through multivariable analyses, and medical chart review may not be an adequate method to determine attributable mortality because of subjectivity (22 ).
When we compared total with partial alcohol attributable fractions, a substantial part 40-988%) of the incidence of alcohol attributable cancer occurred because of alcohol consumption higher than the recommended upper limit in both men and women.
2, 21 We took stringent measures to exclude data that may be attributable to contamination because of the recent reports of a gammaretrovirus infection in clinical samples was subsequently attributed to PCR carry-over with mouse DNA 18 or spread from in vitro infection from a mouse gammaretrovirus derived from a human prostate cancer cell line previously passaged through mice.
This has allowed us to unequivocally show that the embryonic lethality associated with the Byg Gga2 gene-trap allele is not attributable loss of GGA2 because this allele is clearly hypomorphic.
To estimate the PAF of postmenopausal breast cancer for five risk factors combined, summing of the five separate PAFs would lead to an overestimation of the attributable proportion of cases because women may be exposed to more than 1 risk factor.
Lack of replication was not attributable to lack of power, because the post hoc type II errors of missing results of a magnitude as the reported by Briggs et al. [ 22] at the final stage of their analyses were <0.20, which is conventionally considered sufficient (corresponding to statistical power of 0.80).
Among pre-existing conditions, diabetes is a known risk factor 31 and had a higher risk (adjusted relative risk 3.9, 1.7 to 8.9), but a population attributable risk of only 2.0% because of the low prevalence in this cohort.
As illustrated in Fig. 1a, cryosections of F-spores show a clearly distinguishable electron-dense layer of about 14-nm thickness attributable to binding of diacetyl-2,4,5,7-tetraiodo-fluorescein diacetyl-2,4,5,7-tetraiodo-fluorescein diacetyl-2,4,5,7-tetraiodo-fluorescein diacetyl-2,4,5,7-tetraiodo-fluorescein
Two patients stopped sorafenib after relapse and 5 stopped because of attributable toxicities after the DLT period.
The absent fixed effects for the personal characteristics could also be attributable to methodological/statistical issues because of the small sample size at the second level and its possible effects on the accuracy of the estimation.
