A Retrospective Analysis of Lower Limb Deformity Correction using Three-dimensional Computed Tomography Scan.
Article in Annals of African medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionStandard deformity correction is based on full-length true anteroposterior (AP) and lateral radiographs. However, a three-dimensional computed tomography (3D-CT) scan may provide a more intricate and detailed understanding of the deformities, to plan for the accurate correction. We present a retrospective evaluation of the deformities in three-dimensional projection with 3D-CT scans and its application on the correction of malalignment of the lower limbs. MATERIALS AND
methodsPlanning of 107 cases of deformities in the lower limb was done using a 3D-CT scan over a 5-year period from September 2017. Evaluation was done by measuring angles and lines from true AP and lateral image sections of 3D-CT scans instead of standing full length lower limb radiographs (Orthoscanogram). Osteotomies were stabilized with Ilizarov fixation, followed by correction with Hexapod system (ORTHO-SUV, Pitkar, India).
resultsThe use of 3D-CT scan AP and lateral images provided accurate planning for deformity correction. Deformities can be understood in all three planes including rotational malalignment in a single scan.
conclusionThe precise information of the deformity in sagittal, frontal, and rotational planes is obtained by doing a 3D-CT scan, which allows for further precise planning and correction of lower limb deformities.
