Short-term morphological changes of vacuum-formed retainers with different gingival margin designs: a randomized clinical trial.
Trial report in The Angle orthodontist, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Objectives: To investigate the morphological and dimensional changes in vacuum-formed retainers (VFRs) after intraoral aging of 3 months and 6 months and to compare changes between VFRs with conventional and modified gingival margin design. Materials and Methods: Forty-one patients were randomly assigned to two groups: conventional design (CD) and modified design (MD). Preuse and postuse digital models of each VFR were imported to Geomagic Control software to assess the morphological and dimensional changes. Results: In vivo, VFRs underwent significant changes over time. After 3 months, slight expansion of the VFRs was detected, while after 6 months, slight contraction was observed, despite not all parameters resulting in statistically significant differences. No statistically significant differences were found between the CD and MD groups. Conclusions: Intraoral aging affects the dimensional stability of VFRs. The gingival margin design did not impact the morphological and dimensional stability of VFRs over the observed period.
