在受试者入住纽约市养老院后的5年内，研究了痴呆、性别、年龄和功能状态（FS）与死亡率的关系。使用随机抽样的212名疗养院的病人，一个统计模型，以估计死亡的相对风险。当该模型在118名居民的独立样本上进行交叉验证时，它未能显示出显着的拟合不足。鉴于这些结果，通过结合纽约市样本（N = 330）并将其与来自日本东京养老院的样本（N = 363）进行比较，开发了一个国际模型。在纽约模型中，性别是最重要的预测因素，其次是年龄和痴呆; FS不是一个重要的预测因素。尽管纽约和东京疗养院的痴呆症类型有明显差异，但死亡率模式相似。
The relative importance of dementia, gender, age and functional status (FS) was examined for relationships to mortality within five years after admission of the subjects to a New York City nursing home for the aged. Using a random sample of 212 of the nursing home's patients, a statistical model was developed to estimate the relative risk of mortality. When this model was cross‐validated on an independent sample of 118 residents, it failed to show significant lack of fit. Given these results, an international model was developed by combining the New York City samples (N = 330) and comparing them to a sample (N = 363) from a nursing home in Tokyo, Japan. In the New York model, gender was the most important predictor, with age and dementia next in importance; FS was not a significant predictor. Despite the apparent differences in the types of dementia in the New York and Tokyo nursing homes, the mortality patterns were similar.
