An overview of the characteristics and quality assessment criteria in systematic review of pharmacoeconomics
Fig 3
The methodological quality was evaluated by the modified AMSTAR scale in the pharmacoeconomic systematic review.
This plot illustrated the quality of included studies with each judgment ("yes" (score 1), "no" (score 0) and "impossible to judge" (score 0.5)). The overall methodological quality was moderate. Three of the 10 quality items (item 3, item 6 and item 7) were fulfilled in at least 85% of reviews, while 2 items (item 1 and item 9) were fulfilled just about or less than thirty percent.
