The 84 subject-studies and 4,146 individual subjects in this meta-analysis were obtained from nurse-conducted experimental research over an 8-year period. The entire universe of accessible subject-studies that met criteria was included. Although both published and unpublished research were included to protect the study from publication bias, there was no statistically significant difference in findings. The mean effect size for the sample of comparisons from the 84 studies was .59. The associated U3 value of 72.2 and r of .28 indicate that patients who receive research-based nursing interventions can expect 28% better outcomes than 72% of the patients who receive standard nursing care.
本荟萃分析中的84项主题研究和4146名个体受试者来自护士在8年期间开展的实验性研究。纳入了所有符合标准的可获取主题研究。尽管纳入了已发表和未发表的研究以防止研究出现发表偏倚，但研究结果在统计学上并无显著差异。84项研究的比较样本的平均效应量为0.59。相关的U3值为72.2，r值为0.28，这表明接受基于研究的护理干预的患者比72%接受标准护理的患者预期会有28%更好的结果。
