While the assessment of study
quality is encouraged, it is important to point out that such assessment carries
significant subjectivity. Consequently, such analyses should be interpreted with caution.
There are a number of different scales and checklists currently available for the
assessment of study quality (See: Moher D, Jadad AR, Nichol G, Penman M, Tugwell P, Walsh
S. Assessing the quality of randomized controlled trials: An annotated bibliography of
scales and checklists. Controlled Clinical Trials 16:62-73, 1995). |
