Considerable progress has been made on standardizing the capture of each of these by such approaches as the DDF and Biocatalogue, but the community would benefit from coordination to produce full registries combining all these approaches.
Some academic researchers have argued that fuller registries of drug trials are needed because companies, as well as medical journals and scientists, tend to spotlight only trials that show positive results.

Full member registry populations range from a few small registries with <10,000 births per year, to the majority of registries in the range 10 50,000 births, to two registries with 75 90,000 annual births [ 10].
There was full data registry for 31 patients and 33 PC.
In 1978, the Sihui Cancer Registry was established to collect NPC incidence data on all residents, and since 1987, a full cancer registry system has been developed to collect all cancer incidence data through the three-grade cancer prevention network.
Table 1 compares the distribution of selected characteristics among matched SEER-NLMS patients that were included in the incidence analysis with that for the full SEER registry case file originally submitted for matching.
Using the full GP registry population did not result in finding substantial numbers of patients with no emergency admissions in the previous 2 years, but the increased numbers of patients identified included more patients with less prior use and lower levels of morbidity.
Table 6 shows the total number and percentage of cases of NTD (from full EUROCAT registry areas in each of the 12 countries providing data), percentage prenatally diagnosed, median gestation at diagnosis and the number and percentage resulting in termination of pregnancy.
Since 1980, the EUROCAT central database has held individual anonymised records of cases of congenital anomaly occurring for full member registries and aggregate data for associate member registries, including live births, fetal deaths from 20 weeks gestational age, and termination of pregnancy for fetal anomaly.
