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

purposeThis study investigated whether the accuracy of 3D-guided osteotomies is influenced by surgeon experience. Two types of experience were assessed: (1) general surgical experience, defined as self-reported years in practice as an orthopaedic trauma surgeon, and (2) prior use of patient-specific guides (PSGs). Secondary aim was to evaluate whether accuracy varies by anatomical location.

methods24 orthopaedic-trauma surgeons performed 75 corrective osteotomies on cadaveric long-bones (43 single-cut, 32 double-cut; 107 cuts in total). Each osteotomy was preoperatively planned on CT-derived 3D-reconstructions, and PSGs were manufactured to guide the cuts. Postoperative CT-scans were used to compare planned and executed osteotomy planes. Surgeons completed a questionnaire reporting years of practice and annual PSG usage. A Spearman’s rank-order correlation was used to test differences in accuracy versus experience, a Kruskal-Wallis test was performed to explore differences across anatomical locations.

resultsGeneral surgical experience ranged from 0 to 25 years (median 9), and PSG-usage from 0 to 20 cases annually (median 2). No association was found between general surgical experience and osteotomy accuracy (p = 0.406 and p = 0.548). In contrast, PSG-experience correlated with improved accuracy for angular and translational deviation of the osteotomy plane (p = 0.027 and p = 0.029). In addition, midshaft osteotomies of the lower extremity showed smaller angular deviations but larger translational errors compared with metaphyseal (p < 0.001 and p = 0.003).

conclusionExperience with PSGs, rather than general surgical experience, improves accuracy in 3D-guided osteotomies, highlighting the need for training and repeated use. In contrast to metaphyseal, midshaft lower-extremity osteotomies are executed less accurately because fewer anatomical reference points are available.
