-Prize is valid from 6 months from date of draw.
The start of the bacteremic episode was defined as the date of drawing the BC.
In the HCC cohort, overall survival was measured in months from date of CTC blood draw to the date of death with censoring at date of last known vital status if lost to follow-up.
The median overall survival in the HCC cohort was 9.44 months from date of CTC blood draw.
Finally, the laboratory data had some flaws: lack of date of draw for some blood cultures, recording of time of draw and receipt of the blood cultures only by date (and not hour and minute), no possibility to categorize blood culture sets from specimen identification numbers, and lack of speciation of a few microorganisms.
Sera from 150 cases and 314 controls matched on date of blood draw, age at blood draw, and region was used to determine concentrations of 11 OC pesticide metabolites and 34 PCB congeners.
An incident case, therefore, would have either very little or no time from date of diagnosis to date of blood draw.
The mean time from the date of blood draw to the date of diagnosis was 7.1 (SD 3.7) years.
Therefore, we compiled a best-estimate-date, defined as the date of draw, and if this date was missing, the date of receipt (Table 1).
It has also been observed from the work to date that the speed of drawing plays an interesting role, in so far as, the higher is the speed the further is the draw, which is not entirely as expected.
