Dislocation of bipolar hip hemiarthroplasty through a postero-lateral approach for femoral neck fractures: A cohort study.
Trial report in International orthopaedics, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02131987 (Radiological Riskfactors for Dislocation of Hip Hemiarthroplasty Through a Posterolateral Approach as Treatment for Femoral Neck Fracture), which is not on this map.

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

Abstract
purposeTo analyze postoperative global femoral offset (FO), leg length discrepancy (LLD) and Wiberg angle as risk factors for prosthetic dislocation after treatment with bipolar hemiarthoplasty (HA) through a postero-lateral approach for femoral neck fracture (FNF).
methodsThree hundred and seventy three patients treated with a cemented bipolar HA through a postero-lateral approach between January 2006 and December 2013 were included in a cohort study with a follow-up time ranging from 6 months to 7 years. Radiographs and all surgical records were reviewed regarding Global FO, LLD and Wiberg angle. We compared stable hips without dislocation to those with either a single dislocation and those with recurrent instability.
resultsThree hundred and twenty eight hips fulfilled the inclusion criteria and were analyzed in the study. The incidence of prosthetic dislocation was 10.7% (36/373). The mean time from surgery to first dislocation was 3.9 months (0-47) and 62.5% had recurrent dislocations. Patients with dislocation had a statistically significantly decreased postoperative global FO (-6.4 mm vs. -2.8 mm, p = 0.04), LLD (-2 vs. 1.5 mm, p = 0.03) and smaller Wiberg angle (40° vs. 46°, p = 0.01) on the operated side compared with the rest of cohort. In comparison to age and sex-matched control groups from the cohort, the difference in the radiographic parameters were significant in patients with recurrent dislocations but not in patients with a single dislocation.
conclusionPatients with recurrent dislocations had a decreased postoperative global FO, shorter leg and shallower acetabulum on the operated side compared with their controls. These factors might decrease the soft-tissue tension around the operated hip and predispose to dislocation. LEVEL OF EVIDENCE: Therapeutic Level III.
