The average time between the date of return from area endemic for malaria and the onset of symptoms was 16.5 days, ranging between 0 ("directly from the airport") and 164 days.
The number of person-years of follow up was ascertained based on the interval between the date of return of the 1980 questionnaire and the date of diagnosis of RA (as defined in the medical record), death, the end of the study period (1 June 2002), or loss to follow up (defined as no further return of questionnaires) for each participant.
Cases diagnosed between date of 1986 questionnaire return and 31 December 2000 were included in this report (n=328).
In our study, a patient was classified as LTFU if the patient had been followed up at least once after ART initiation, but had not had contact with the clinic for 180 days or more since their last recorded expected return date, or if there were 180 days or more between the expected date of return and the next clinic visit.
The date of return differed between the two years; individuals arrived from November 2nd to December 15th in 2006, but arrived earlier from October 1st to November 20th in 2007.
The compliance index was calculated as the percentage of the rated drug doses taken between the date of dispensation and the date of return of the study drugs.
Reproductive success and the mode, direction and strength of selection on date of return and body length differed between two cohorts sampled in 2006 and 2007.
Our results have shown that reproductive success, as well as selection on body size and date of return to the spawning ground differed markedly between two parental cohorts.
Loss to Follow-up (LTFU) was defined as "a patient who had been followed up at the sentinel site, who had not had contact with the health facility for 180 days or more since their last recorded expected date of return or if there were 180 days or more between the expected date of return and the next clinic visit".
L. 107 16, § 401(f)(2)(B), substituted "certain date" for "due date of return" in heading.
