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
objectiveThe management of femoral multiplanar deformity remains a great challenge for orthopaedic surgeons. The focal dome osteotomy (FDO) combined with Ilizarov technique is a theoretically ideal method for treating femoral multiplanar deformity, but the clinical evidence is limited. The aim of this study is to assess the clinical and radiological outcomes of this combined strategy for correcting femoral multiplanar deformities.
methodsA retrospective analysis was conducted to analyze 20 patients (29 limbs) with femoral multiplanar deformities treated by FDO combined with Ilizarov external fixation in our limb deformity center between 2017 and 2022. Preoperative and postoperative radiographical parameters were measured, including lateral proximal femoral angle (LPFA), mechanical lateral distal femoral angle (mLDFA), middle diaphysis angle (MDA), anatomic posterior distal femoral angle (aPDFA), mechanical axis deviation (MAD), and limb length discrepancy (LLD). Clinical assessments included a self-made questionnaire for exercise capacity score (ECS), visual analog scale (VAS), and the 36-Item Short-Form Health Survey (SF-36) score.
resultsThere were eight males and 12 females, with a mean age of 32.8 years (14-61 years). All patients completed follow-up with a mean follow-up duration of 41.5 (27-81) months. The mean EFT was 8.9 (1.4-20.2) months. At final follow-up, significantly improvement was noted regarding mean LLD (from 1.8 to 0.4 cm, p < 0.05), MDA (from 31.8° to 10.4°, p < 0.05), aPDFA (from 97.6° to 91.8°, p < 0.05), MAD (from 22.4 to 5.3 mm, p < 0.05), CORA on the true deformity plane (from 32.4° to 6.8°, p < 0.05). The mean VAS was decreased from 4.03 (2.0-6.0) preoperatively to 1.38 (0-3.0) at final follow-up (p < 0.05). The mean score of each item of SF-36 was significantly improved at final follow-up (p < 0.05). The mean ECS was improved from 8.2 (5-12) preoperatively to 11.4 (8-13) at final follow-up (p < 0.05). During the follow-up, one patient underwent pin exchange. One patient underwent internal fixation to replace the Ilizarov fixation 1.4 months after the first surgery. Residual LLD (>0.5 cm) was noted in four patients but without significant symptoms. No serious complications occurred.
conclusionsThe strategy of FDO combined with Ilizarov fixation could provide powerful ability and good flexibility for correcting femoral multiplanar deformities without significant complications.
