Radiographic risk factors for predicting failure of geriatric intertrochanteric fracture treatment with a cephalomedullary nail.
Article in Journal of the Chinese Medical Association : JCMA, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
backgroundThe cephalomedullary nail is the most common device used to treat unstable intertrochanteric fractures (ITFs) (AO/OTA 31-A2 and A3) in the geriatric population. However, there is lack of radiological parameter to evaluate the entry point; hence, this study reports a new radiological parameter to evaluate the entry point of the nail. Besides, other risk factors were also examined.
methodsA retrospective study on the geriatric population with unstable ITFs was conducted from July 2011 to December 2014. A total of 136 patients were enrolled in this study; they received treatment with Gamma-3 nails (Stryker, Mahwah, NJ, USA) and were followed for at least 1 year. Demographic data, radiological parameters, and side-difference of the distance from the piriformis fossa to the greater trochanteric tubercle in the anteroposterior view (dPG) were compared between the union and failure groups. Student's t test, χ test, and multiple logistic regression were used in the statistical analyses.
resultsThe overall failure rate was 13.23% (18 patients). Sex, tip-apex distance (TAD), and dPG were significantly different between the failure and union groups in multivariate analyses. Using a dPG > 6 mm as a reference, patients with a dPG > 6 mm had an odds ratio of 7.64 for failure relative to a dPG < 6 mm.
conclusionThis study provides additional evidence demonstrating that sex and TAD have significant effects on the outcomes of unstable ITFs after nailing. Moreover, the newly reported radiological parameter, dPG, can be used to predict the failure of ITFs treated using cephalomedullary nails.
