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
Objective: The aim of this study was to evaluate whether the locking femoral neck plate (LFNP) can be an alternative fixation method to the cannulated screws with a medial buttress plate. For this purpose, we compared biomechanically the LFNP and cannulated screws with or without a medial buttress plate in Pauwels type 3 femoral neck fractures. Methods: A vertical fracture model was created at an 80-degree angle to the femoral neck in 28 synthetic bone models. The models were randomly divided into 4 groups, each containing 7 bones each. The bone fracture models were fixed with 3 parallel cannulated screws in group 1, 3 parallel cannulated screws combined with a medial buttress plate in group 2, LFNP in group 3, LFNP combined with a medial buttress plate in group 4. The stability of the specimens was tested biomechanically at a 7° valgus inclination to simulate normal 2-legged weight-bearing through an anatomical femur. The forces corresponding to 0.5 mm, 1 mm, 1.5 mm, and 2 mm displacement and failure loads were calculated in all groups. Results: The axial load values corresponding to 4 di!erent fracture displacements and the failure load values of the groups were compared, group 1 was significantly weaker (P < .05 for each) while group 4 was significantly stronger (P < .05 for each) compared to the other groups. There was no statistically significant di!erence between group 2 and group 3 (P > .05 for each). Conclusion: The results of this biomechanical study showed that the LFNP fixation system provided su"cient biomechanical stability for unstable Pauwels type 3 femoral neck fractures. The biomechanical performance of LFNP was similar to that of cannulated screws with medial buttress plate and better than that of cannulated screws alone. This suggests that LFNP can be a promising stable alternative fixation method to cannulated screws with a medial buttress plate in unstable femoral neck fractures.
