Fig. 2From: Effect of bisphosphonate treatment of titanium surfaces on alkaline phosphatase activity in osteoblasts: a systematic review and meta-analysisForest plot of the association between bisphosphonate coating and ALP response ratio after 7 days. ALP response ratio was calculated as the ratio of ALP activity measured in the treatment group to that measured in the control group. Response ratios > 1 indicate higher ALP activity in the treatment group as compared to the control group. RR – response ratio; CI – confidence intervalBack to article page
