title: A meta-analysis of two different trials on posterior resin-bonded bridges.
abstract: In a meta-analysis the results of two different trials on posterior resin-bonded bridges (PRBBs) were combined. The common experimental variable 'preparation form' and the variable 'location' were combined for this analysis. The meta-analysis showed a highly significant effect for the variable 'location' (P < 0.001). Although the experimental variable 'preparation form' had no significant influence in the separate trials, the combined study revealed a significant effect for this variable on the retention of PRBBs (P = 0.03).
