Table 1 compares the 5-HTTLPR distributions for our Taiwan sample with other samples from diverse populations. These studies emerged from a PubMed search for distributions of the 5-HTTLPR polymorphism for specified racial or ethnic groups. For studies that reported distributions for control and patient samples, we present results for the controls. In contrast to the Taiwan study, which is based on a national sample, the other studies comprise various sampling strategies (e.g., convenience, clinical, and community samples). Sample sizes range from fewer than 100 to more than 1000 participants in the Taiwan sample and two Caucasian samples.
