[Application of capture-recapture method on injury control].
OBJECTIVE
To explore relationships among several capture-recapture methods to be used in injury studies.


METHODS
Comparing the method on the estimation number of missed cases with supergeometric distribution and proportional methods and study the relationship between the three methods.


RESULTS
Results from estimation method for number of missed cases and supergeometric distribution were identical while the formula of estimation method for number of missed cases could be induced from one of supergeometric distribution formula. The distribution of injured population did not belong to the negative binomial distribution. The estimation range was not the same between proportional method and supergeometric distribution.


CONCLUSIONS
Either supergeometric distribution or estimation method for number of missed cases could be chosen, but the former was simple in calculation. Considering the estimating range was not the same between supergeometric distribution and proportional method, conditions for application must be considered during implementation.
