The special characteristics, endpoints considered and problems of current lower-tier tests are described and discussed.
Table 1 shows a comparison of demographic and clinical characteristics by endpoints.
The clinical characteristics and endpoints of the AD patients according to living status are shown in Table 3.
Finally, we examined discrepancies between study characteristics, primary endpoints, and results as reported in the summaries and publications.
Main outcome measures Clinical trial characteristics, primary endpoints, and safety and efficacy results in the FDA documents and corresponding publications.
Trials had heterogeneity regarding investigation periods, baseline characteristics, and endpoint reporting, with a lack of information at long term follow-up.
The retrieved literature was carefully reviewed, and various information was extracted for each examined study, including the study's first author, publication year, sample size, study type, population characteristics, study endpoint, and HR/RR values and 95% confidence intervals (CIs) (or a contingency table).
This goes some way towards satisfying another desirable characteristic of surrogate endpoints, namely, that they should relate linearly to the true endpoint.
Endpoints characteristic of the initiation of apoptosis were monitored for a period of 24 h following medium transfer.
On the other hand, SDPs enable applications to dynamically discover the existence, characteristics, and communication endpoints of services.
