荟萃分析综合了多项初步研究并确定关系模式。荟萃分析必须解决主要研究方法学质量的差异，以产生有意义的结果。不存在解决这些质量差异的单一标准。质量测量尺度充满了开发和应用问题。已经提出了几种解决质量问题的策略。研究人员可以设定最低纳入水平或要求存在某些质量属性。一种包容性方法是通过质量得分来衡量效果大小。这允许纳入不同的研究，但依赖于有问题的质量措施。通过将质量视为一个实证问题，荟萃分析师可以检查质量和效应大小之间的关联，从而保留荟萃分析系统地检查数据的目的。研究人员越来越多地结合策略来克服使用单一方法的局限性。未来制定主要研究质量维度的有效衡量标准的工作将提高荟萃分析为研究和护理实践提供信息的能力。 (C) 2003 年 Wiley 期刊公司。
Meta-analyses synthesize multiple Primary studies and identify patterns of relationships. Differences in primary study methodological quality must be addressed for meta-analysis to produce meaningful results. No single standard exists for addressing these quality variations. Quality measurement scales are fraught with development and application Problems. Several strategies have been proposed to address quality. Researchers can set minimum levels for inclusion or require that certain quality attributes be present. An inclusive method is to weight effect sizes by quality scores. This allows the inclusion of diverse studies but relies on questionable quality measures. By considering quality an empirical question, meta-analysts can examine associations between quality and effect sizes and thus preserve the purpose of meta-analysis to systematically examine data. Researchers increasingly are combining strategies to overcome the limitations of using a single approach. Future work to develop valid measures of primary study quality dimensions will improve the ability of meta-analysis to inform research and nursing practice. (C) 2003 Wiley Periodicals, Inc.
