Cast metal posts versus glass fibre posts: which treatment of choice based on cost-minimisation analysis?
Article in Evidence-based dentistry, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Aim The aim of this randomised clinical trial based on cost-minimisation analysis was to assess and compare four post-retained restorative strategies for endodontically treated teeth.Methods A total of 225 endodontically treated teeth in 141 patients were evaluated annually between 2009 and 2018. In this sense, the teeth were divided into four groups according to the treatment strategy, where three groups were treated with glass fibre posts in combination with composite resin restorations or single metal-ceramic crown with or without ferrules, and one group was treated with cast metal posts with metal-ceramic crowns. According to the outcome of the treatment during follow-up, the teeth received additional treatments, which ranged from restoration repair, re-cementation, endodontic retreatment, apical surgery, post/crown replacement to tooth extraction and replacement through metal-ceramic implant-supported crown. Thus, cost-minimisation analysis was based on November 2018 values from the Brazilian Public Health System, considering the primary costs related to the post, restoration or crown, and incremental costs related to the outcomes during follow-up.Results Primary treatment costs were lower for the group using glass fibre posts in combination with composite resin restorations (US$27.11), while the highest costs were for the group using cast metal post with metal-ceramic crown (US$153,14). In turn, the incremental costs due to tooth removal, implant placement and metal-ceramic crown (US$363.92) were the highest, while the lowest costs were related to procedures for crown re-cementation (US$6.11) followed by repair of the resin restoration (US$16.47). In this regard, the highest percentage of failures was related to restoration fractures in the glass fibre posts in combination with the composite resin restorations group. However, the average annual cost was significantly lower in the group that used glass fibre posts in combination with composite resin restorations (p <0.001) when compared to the other groups, with or without ferrules.Conclusions The treatment of endodontically treated teeth using glass fibre posts in combination with composite resin restorations presented a significantly lower average annual cost when compared to treatments that consider the use of cast metal posts, metal-ceramic crowns, with or without ferrules.
