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

backgroundSegmental Le Fort I osteotomy combined with anterior maxillary clockwise rotation has been proposed as an effective treatment for maxillary hypoplasia. However, the stability of maxilla after the operation remains unknown.

methodsA total of 30 patients undergoing segmental Le Fort I osteotomy were retrospectively included. The follow-up period was more than one year. The stability of anterior maxilla after clockwise rotation was evaluated by cone beam computed tomography (CBCT) performed before surgery (T0), three days after surgery (T1), and at least one year after surgery (T2), respectively. The key parameters were the postoperative relapse of the anterior maxillary clockwise rotation angle (CRA) and paranasal advancement.

resultsFollowing segmental Le Fort I osteotomy, the average CRA of the anterior maxilla was 10.02° ± 3.86°, while the mean paranasal advancement was 6.22 ± 1.40 mm. At the one-year follow-up, the relapse of CRA and paranasal advancement were -0.42° ± 2.51° (p = 0.951) and -0.28 ± 0.83 mm (p = 0.08), respectively, suggesting good postoperative stability. Additionally, no significant correlation was found between the intraoperative CRA and its relapse over time.

conclusionSegmental Le Fort I osteotomy combined with anterior maxillary clockwise rotation demonstrates favorable stability up to one year postoperatively, making it a reliable approach for the treatment of maxillary hypoplasia.
