The overall outcome of the computed data sets suggest no difference between the caries-preventive effects of GIC- and resin-based fissure sealants .
Background This article constitutes a partial up date of the original systematic review evidence by Yengopal et al. from 15 January 2008 ( published in the Journal of Oral Science in 2009 ) with primary focus on research quality in regard to bias risk in trials .
Its aim is to up date the existing systematic review evidence from the English literature as to whether caries occurrence on pits and fissures of teeth sealed with either GIC or resin is the same .
Evidence favoring the use of anticoagulants in the hospital phase of acute myocardial infarction.
Since the last comprehensive review of anticoagulation in acute myocardial infa rct ion four additional r and omized control trials have been reported . The overwhelming majority of all trials favored anticoagulation .  Rates of thromboembolism were higher in the control , and hemorrhagic complications in the anticoagulated group . Pooling of all r and omized control trials gives mean case fatality rates of 19.6 % for the control and 15.4 % for the anticoagulated group , a relative reduction of 21 % ( P less than 0.05 or less than 0.001 , depending on the analytic method ) . Five of six r and omized control trials reported " no effect " because the difference favoring anticoagulation was not statistically significant . However , sample sizes in these " negative " papers were too small to protect against missing a 21 % reduction in true case fatality rate due to anticoagulation ( beta greater than 0.10 ) . All patients who present no specific contraindication should receive  anticoagulants  during hospitalization for infa rct ion
