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
purposeThis study describes the minimally invasive Dega osteotomy for treating residual acetabular dysplasia in ambulatory pediatric patients. The focus is on assessing the safety, feasibility, and early outcomes of this minimally invasive technique.
methodsA prospective series was conducted in a single tertiary orthopaedic center. The procedure involved an initial examination of hip joint stability using intraoperative arthrography. The surgical procedure involved a small transverse incision distal and lateral to the anterior superior iliac spine, followed by a Dega osteotomy and bone allografting. Variables such as surgical time, blood loss, incision length, and acetabular index were measured.
resultsIn healthy ambulatory patients, 16 osteotomies were performed on 12 patients with an average age of 32 months. The mean incision length was 2.3 cm, average blood loss was 17 mL, and mean surgical time was 21 minutes per side. Preoperative and postoperative acetabular indices averaged 40.3° and 18.6°, respectively. The mean follow-up period was 13 months. No complications were seen in this series.
conclusionThe minimally invasive Dega osteotomy technique is a safe and effective method for treating residual acetabular dysplasia in ambulatory patients. It offers advantages of minimal invasiveness, reduced surgical time, and less blood loss, with outcomes comparable to standard methods. However, further studies with larger cohorts and longer follow-up are necessary to fully establish its efficacy and safety profile.
