中文摘要 | 整合分析的使用時機在於當各研究觀點交集少時,以及要結合多數小樣本研究的情況下;其研究限制要考慮到出版偏差、選擇偏差、無法取得原始資料、研究的時空因素、各研究文獻中可能有不同的相關因子和文獻之篇數不多或總樣本數不足等問題。整合分析中用來整合研究數據的統計方法有許多種,都是用來整合估計值 (effect size),估算此估計值的變異數 (variance),進而執行統計檢定,主要有固定作用模式 (fixed effect model) 及隨機作用模式 (random effect model) 兩個大方向。 |
英文摘要 | It's the timing to use the meta-analysis when the reviewed researches have poor cumulation and when we would like to combine some researches with small effects. The limitations of meta-analysis are publication bias, selection bias, the missing original data of primary studies, the differences in when and where the trials were conducted, the different relative factors among studies, and the problems of insufficient reviewed articles or total samples. There are some statistic methods of integrating the data. They were used to calculate the effect size and variance. The main directions are fixed effect model and random effect model. |
