Accuracy and stability of virtual surgical planning for maxillary advancement in patients with cleft lip and palate: a systematic review and meta-analysis.

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
backgroundCleft lip and palate (CLP) frequently cause maxillary hypoplasia, requiring surgical advancement, and virtual surgical planning (VSP) is increasingly used to improve accuracy. This systematic review and meta-analysis synthesized the evidence on VSP-assisted maxillary advancement in patients with CLP, with surgical accuracy as the primary outcome and skeletal stability, intraoperative efficiency, complications, patient-reported outcomes, and software utility as the secondary outcomes.
methodsThis review followed the PRISMA 2020 statement and was prospectively registered (PROSPERO CRD420251011475). PubMed, Scopus, Web of Science, Embase, and ScienceDirect were searched. Methodological quality and certainty of evidence were assessed. Conventional osteotomy and distraction osteogenesis were analyzed separately; an exploratory random-effects meta-analysis was performed only for the homogeneous conventional Le Fort I osteotomy subset.
resultsTwelve studies were included. VSP achieved clinically acceptable accuracy, with mean linear deviations of 0.05-2.75 mm and most angular deviations below 4°. In the conventional Le Fort I subset, random-effects pooling with Hartung-Knapp adjustment gave mean absolute deviations of 0.65 mm mediolaterally (95% CI 0.58-0.73) and 1.10 mm superoinferiorly (0.49-1.71), both highly consistent (I
conclusionCurrent evidence supports the accuracy and feasibility of VSP-assisted maxillary advancement in patients with CLP; however, it is insufficient to prove reduced relapse or superiority over conventional planning. Because certainty is low to very low, VSP should be regarded as a promising adjunct rather than a proven standard of care; adequately powered prospective comparative studies with standardized outcomes are needed.
