Visualization of a cam-type femoroacetabular impingement while squatting using image-matching techniques: a case report.
Article in Skeletal radiology, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
The in vivo assessment of the three-dimensional (3D) kinematics of the hip in patients with femoroacetabular impingement (FAI) under weight-bearing conditions has not been previously reported. We evaluated the pre- and postoperative hip kinematics of a 34-year-old man, with a cam-type FAI while squatting, using image-matching techniques with measurement of the rim-neck distance. Post-osteochondroplasty, the α-angle improved from 51.0° to 35.5° and the head-neck offset ratio from 0.04 to 0.23. Coxalgia during squatting disappeared, and the Harris Hip Score improved from 79 to 92 at 1 year post-surgery. Postoperative hip kinematic values (3.8° of posterior pelvic tilt and 101.2° of femoral flexion at 96.8° of maximum hip flexion) were similar to the preoperative values (2.9° of posterior pelvic tilt and 102.7° of femoral flexion at 98.8° of maximum hip flexion). Meanwhile, osteochondroplasty improved the minimum rim-neck distance at maximum hip flexion from 2.0 to 10.4 mm. In vivo 3D visualization of the clearance between the femoral head-neck junction and the acetabulum could assist surgeons in adequately identifying the location of impingement and confirming sufficient resection post-operatively.
