Critical Bone Defect Affecting the Outcome of Management in Anatomical Type IV Chronic Osteomyelitis.
Article in Strategies in trauma and limb reconstruction. 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
Background: The Cierny and Mader classification assists with decision-making by stratifying host status and the pathoanatomy of the disease. However, the anatomical type IV represents a heterogenous group with regard to treatment requirements and outcomes. We propose that modification of the Cierny and Mader anatomical classification with an additional type V classifier (diffuse corticomedullary involvement with an associated critical bone defect) will allow more accurate stratification of patients and tailoring of treatment strategies. Methods: A retrospective review of 83 patients undergoing treatment for Cierny and Mader anatomical type IV osteomyelitis of the appendicular skeleton at a single centre was performed. Results: Risk factors for the presence of a critical bone defect were female patients [OR 3.1 (95% CI, 1.08-8.92)] and requirement for soft tissue reconstruction [OR 3.35 (95% CI, 1.35-8.31)]; osteomyelitis of the femur was negatively associated with the presence of a critical bone defect [OR 0.13 (95% CI, 0.03-0.66)]. There was no statistically significant risk of adverse outcomes (failure to eradicate infection or achieve bone union) associated with the presence of a critical-sized bone defect. The median time to the bone union was ten months (95% CI, 7.9-12.1 months). There was a statistically significant difference in the median time to bone union between cases with a critical bone defect [12.0 months (95% CI, 10.2-13.7 months)] and those without [6.0 months (95% CI, 4.8-7.1 months)]. Conclusion: This study provided evidence to support the introduction of a new subgroup of the Cierny and Mader anatomical classification (Type V). Using a standardised approach to management, comparable early outcomes can be achieved in patients with Cierny and Mader anatomical type V osteomyelitis. However, to achieve a successful outcome, there is a requirement for additional bone and soft tissue reconstruction procedures with an associated increase in treatment time.
