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 clinical management of partial bone defects in lower limbs, particularly those resulting from osteomyelitis, remains a significant challenge. This study aimed to systematically evaluate the effectiveness of 3D-printed porous Ti6Al4V prostheses in addressing osteomyelitis-induced partial bone defects.
methodsWe established a comprehensive protocol for utilizing 3D-printed prostheses for bone defect repair, encompassing 3D simulation of prosthesis implantation and internal fixation, finite element analysis (FEA), and clinical implementation. Mimics software facilitated simulation of fixation patterns and screw lengths. FEA modeled bone defects in the distal metaphyseal femur and distal diaphyseal tibia to assess changes in stress conduction pre- and post-prosthesis implantation. The clinical study involved eight patients (average age: 56.3 years) with an average defect length of 14.9 cm. Postoperative outcomes were evaluated using X-rays and the Lower Extremity Functional Scale (LEFS).
resultsFEA demonstrated that the implanted prostheses effectively shared stress and reduced the load on residual bone in both models, thus lowering the risk of fractures under external forces. The average follow-up period was 24.5 months, with patients initiating weight-bearing activities on average 7.8 days post-surgery. Serial postoperative X-rays demonstrated long-term stability of the prostheses, with progressive bone regeneration around and integration with the prostheses. While two patients experienced infection recurrence requiring prosthesis removal and debridement, the remaining six showed significant improvement in LEFS scores, increasing from 31.5 preoperatively to 61.0 at the last follow-up.
conclusions3D-printed porous Ti6Al4V prostheses effectively restore anatomical integrity and optimize stress conduction in lower limbs, resulting in substantial functional recovery. This innovative approach shows promise for wider clinical adoption and warrants further investigation in medical practice.
