Other validation studies used an interval between from 1 to 4 days for OSS, and from 2 to 7 days for SPADI.
We used the interval between the last dead bird and the sample collection dates as a potential reflection of the survival of the virus in a natural setting.
In this study, we were unable to directly determine time to pregnancy in our cohort, and instead used the interval between first and second child as we expect that this time is, for the most part, unintentional waiting time.
Professor Mitch Dowsett and colleagues [ 2] addressed the topic of 'short-term preoperative treatment for all', in which the approach is to use the interval between time of diagnosis and surgery to employ treatment, and to measure the effect on proliferation and/or other molecular markers in tumour biopsies.
One of their chief concerns, apparently, is that republicans may try to use the interval between the death of the old monarch and the coronation of the new one to whip up anti-royal sentiment.
Mr. Bush seems to be planning to use the interval between presidential debates to offer up all the rejoinders he'd have fired at Mr. Gore on Tuesday if only he'd thought of them.
In [6], another alternative is to probe routes end-to-end and use the interval between packet arrivals to calculate the route capacity.
Taking into account repeated measurements of each individual and adjusting for covariates, a mixed model using the interval between initiation of treatment and 9-month follow-up showed regression estimates of −0.16 mmHg (95% CI, −0.69 to 0.38 mmHg) in systolic blood pressure and 0.19 mmHg (95% CI, −0.27 to 0.66 mmHg) in diastolic blood pressure per 10-μg/dL blood lead increase.
We used longer intervals between the casts than in the standard method.
Studies of test-retest reliability for health-related quality of life instruments have used varying intervals between test administrations.
Finally, we also investigated how any decline in antibody titers might affect the proportion of seroconversions detected had we used longer intervals between sampling time-points, by computing the number with 4-fold or greater rise in titers when independently comparing samples B and C against the pre-epidemic sample taken before the initial epidemic of infections which started in mid-June mid-June 2009
