Cox regression analysis showed that OCT4 was an independent risk factor (hazard ratio = 11.23, 95 % CI, 1.31 - 95.6; p = 0.027) for overall survival while SOX2 overexpression showed low hazard ratio for death (hazard ratio = 0.220, 95 % CI, 0.06 0.72; p = 0.013).
The state, which has since passed legislation that makes it virtually impossible to build private dams, classifies them in three categories: high hazard, significant hazard and low hazard.
"It may be a low hazard, but it's not completely benign".
The rest of the dams are considered "low hazard," posing little risk to lives or property.
area was occupied by very low hazard zone, 69.77 sq.
area was under low hazard zone, 51.13 sq.
Peter Exley, from the RSPB, said although PIB was classified as "very low-hazard" the impact it had had on birds showed it was "clearly not low hazard".
Nonetheless, a low bioavailability/bioaccessibility fraction should not be interpreted as representing a low hazard potential.
This factor was worse (i.e. giving a high hazard ratio: 1.05 in hormone therapy, 2.88 in chemotherapy, and 2.07 in chemotherapy plus hormone therapy) in univariate analysis, and better (giving a low hazard ratio: 0.64 in hormone therapy, 0.8 in chemotherapy, and 0.66 in chemotherapy plus hormone therapy) in multivariate analysis.
However, they tended to learn imperfectly, over-estimating low hazard rates and under-estimating high hazard rates.
