Surgical Outcomes of Internal Fixation Using Multiple Screws in Femoral Neck Fractures with Valgus Impaction: When Should We Consider Hip Arthroplasty? A Retrospective, Multicenter Study.
Article in Hip & pelvis, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeWe analyzed the surgical outcomes at two institutions after internal fixation using multiple screws in femoral neck fractures with valgus impaction to determine independent predictors and their cut-off values for nonunion and reoperation. MATERIALS AND
methodsBetween January 2006 and December 2016, 104 femoral neck fractures with valgus impaction that underwent internal fixation using multiple screws from two institutions were enrolled. The multiple logistic regression model and receiver operating characteristics analysis were used to determine the independent predictors and cut-off values for nonunion and reoperation.
resultsThere were 20 reoperations (19.2%) due to 11 nonunions (10.6%) and nine cases of femoral head osteonecrosis (8.7%). Multiple logistic regression analysis revealed that independent predictors of nonunion and reoperation were age and posterior tilt angle (
conclusionPrimary hip arthroplasty should be considered in patients older than 73 years of age with a posterior tilt angle greater than 13°.
