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: It is not clear whether cortical fibular allografts or cancellous femoral allografts provide similar stability for augmentation of locking plate fixation of proximal humerus fractures. Therefore, this study aimed to assess and compare biomechanical properties of augmented locking plate fixation with 1) a cortical fibular allograft and 2) a cancellous femoral allograft. Methods: Twenty-two fresh frozen humeri were randomly allocated to undergo unstable three-part fracture creation, locking plate fixation, and augmentation with cortical fibular or cancellous femoral allografts. All constructs were tested with cyclic loading (5 N to 532.5 N) for 1000 cycles at 1 Hz. Subsequently, constructs were loaded to 1700 N. Loss of humeral head height (HHH), ultimate failure loads, mode of failure, and stiffness were assessed. Results: Twenty humeri were included in the analysis. No failure occurred during cyclic loading. During load-to-failure testing, four (40.0%) fibula-augmented constructs and six (60.0%) femoral-augmented constructs failed. During cyclic loading, median loss of HHH was 2.00 (interquartile range [IQR], 1.12-3.50) for fibular grafts and 2.75 (IQR, 2.00-3.00) femoral grafts ( Conclusion: There is no significant difference in biomechanical stability between cortical fibular allograft augmentation and cancellous hip allograft augmentation for locking plate fixation in proximal humerus fractures. Both techniques may equally prevent loss of reduction and early screw protrusion. Cancellous femoral allografts may yield advantages considering costs, availability, and future revision surgery with arthroplasty when compared to cortical fibular allografts.
