1 · What the graph read from it

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.

2 · The registry

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

backgroundSuccessfully restoring facial contours continues to pose a significant challenge for surgeons. This study aims to utilize head-mounted display-based augmented reality (AR) navigation technology for facial soft tissue defect reconstruction and to evaluate its accuracy and effectiveness, exploring its feasibility in craniofacial surgery.

methodsHololens 2 was utilized to construct the AR guidance system for facial fat grafting. Twenty artificial cases with facial soft tissue defects were randomly assigned to Group A and Group B, undergoing filling surgeries with the AR guidance system and conventional methods, respectively. All postoperative three-dimensional models were superimposed onto virtual plans to evaluate the accuracy of the system versus conventional filling methods. Additionally, procedure completion time was recorded to assess system efficiency relative to conventional methods.

resultsThe error in facial soft tissue defect reconstruction assisted by the system in Group A was 2.09 ± 0.56 mm, significantly lower than the 3.23 ± 1.15 mm observed with conventional methods in Group B (p < 0.05). Additionally, the time required for facial defect filling reconstruction using the system in Group A was 25.45 ± 2.58 min, markedly shorter than the 37.05 ± 3.34 min needed with conventional methods in Group B (p < 0.05).

conclusionThe visual navigation offered by the fat grafting AR guidance system presents obvious advantages in facial soft tissue defect reconstruction, facilitating enhanced precision and efficiency in these filling procedures.
