The capture-recapture estimated hospitalization rate was 2.4 (95% CI 1.8 3.8) per 1,000 children <5 years of age (Table 1).
This age distribution was applied to the capture-recapture estimated total cases to derive age-specific estimates for children <6 months, 6 23 months, and 24 59 months of age.
The Downing method shares many characteristics with our integrated modeling approach (e.g., both model harvest rates as a function of age and time), and one might argue that the trends from the Downing method could be scaled by the mark-recapture estimates to provide a similar depiction of population abundance over time.
Mark and recapture estimates of total population sizes from Pachón (O1) and Yerbaniz (O2) caves were similar to our estimates, with averages of 8.5 × 103 individuals and broad 95% confidence intervals ranging from about 1.5 × 103 to 17.0 × 103 [ 7].
Cross type recapture estimates, excluding inbred cross types, were tested for dependence on the percentage of local genes using linear regressions (lm) using the initial release number of unfed fry for the cross types as weights.
PGR designed the study and drafted the manuscript; JM collected all the notifications, performed the record linkage and conducted the statistical analyses except for the capture recapture; EF analysed the case history of hospitalisation and analysed all clinical records; AF and ES performed the capture recapture estimates; FC and PB contributed to the study design and to the manuscript.
Age at recapture was estimated under the assumptions: (1) the birthmark was formed prior or shortly after parturition, (2) the second band was formed 6 months later during the first winter, and (3) the third band was formed 1 year later.
The capture-recapture model estimated underreporting at 17.2% of the overall incidence.
The capture-recapture method estimated a total of 104 subjects (10).
A capture-recapture analysis estimated the breast cancer case ascertainment rate in our cohort to be 95% [ 31].
The capture-recapture analysis estimated 38 cases missed by both systems, yielding 909595% CI 67 145) influenza hospitalizations of children <5 years of age.
