Biomechanical Evaluation of Additional Surgical Maneuvers to Improve Symmetry in Performing Nuss Procedure for Asymmetric Pectus Excavatum.
Article in Eplasty, 2023. 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
Background: Severing part of the thorax prior to bar placement is effective to improve outcomes in performing the Nuss procedure for asymmetric pectus excavatum. This study aims to elucidate the patterns of severing to provide an ideal outcome. Methods: Three-dimensional biomechanical computer models were produced simulating the thoraxes of 10 actual patients with asymmetric pectus excavatum. Virtual surgical operation was performed on the 10 models in 4 patterns: group 1-no part of the thorax was severed (default group). Group 2-The sternum was severed (sternum-severing group). Group 3-The ribs on the affected side were severed (rib-severing group). Group 4-Both the sternum and ribs on the affected side were severed (sternum/rib-severing group). After performing this preparation, simulation of bar placement was performed. Comparing the pre- and postoperative shapes of the models, we examined whether symmetry improved for each group. Results: Symmetry of the chest wall improved for rib-severing group and sternum/rib-severing group. Asymmetry remained for default group and sternum-severing group. Conclusions: Performance of the Nuss procedure for asymmetric pectus excavatum does not greatly improve symmetry of the chest wall. Severing the ribs as an additional maneuver is effective to improve symmetry.
