No difference in flexion power despite iliopsoas fatty degeneration in healed hip fractures with large lesser trochanter displacement.
Article in European journal of orthopaedic surgery & traumatology : orthopedie traumatologie, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 1 of them a synthesis that pooled it.
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
objectiveTo evaluate iliopsoas atrophy and loss of function after displaced lesser trochanter fracture of the hip.
designCohort study.
settingDistrict hospital. PATIENTS: Twenty consecutive patients with pertrochanteric fracture and displacement of the lesser trochanter of > 20 mm.
interventionFracture fixation with either an intramedullary nail or a plate. OUTCOME MEASUREMENTS: Clinical scores (Harris hip, WOMAC), hip flexion strength measurements, and magnetic resonance imaging findings.
resultsCompared with the contralateral non-operated side, the affected side showed no difference in hip flexion force in the supine upright neutral position and at 30° of flexion (205.4 N vs 221.7 N and 178.9 N vs. 192.1 N at 0° and 30° flexion, respectively). However, the affected side showed a significantly greater degree of fatty infiltration compared with the contralateral side (global fatty degeneration index 1.085 vs 0.784), predominantly within the psoas and iliacus muscles.
conclusionSevere displacement of the lesser trochanter (> 20 mm) in pertrochanteric fractures did not reduce hip flexion strength compared with the contralateral side. Displacement of the lesser trochanter in such cases can lead to fatty infiltration of the iliopsoas muscle unit. The amount of displacement of the lesser trochanter did not affect the degree of fatty infiltration. LEVEL OF EVIDENCE: II.
