Fig. 4From: 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 21 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
