Calcific tendonitis of the quadriceps tendon.
Article in Journal of surgical case reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
A 61-year-old woman presented with chronic anterior pain and stiffness in the distal left thigh. Examination revealed swelling and tenderness immediately proximal to the patella. Radiographs showed opacities in the distal anterior thigh whilst MRI identified enlargement of the distal quadriceps tendon with splayed fibres separated by solid conglomerates. Dystrophic calcification of the quadriceps tendon was diagnosed. Blood tests revealed no systemic abnormalities in calcium handling. Arthroscopy of the left knee identified calcific deposits in the supra-patella pouch with surrounding synovitis. An open debridement of the tendon was performed; biopsy of the excised tendon showed chronic tenosynovitis with dystrophic calcification without evidence of malignancy. Post-operatively her knee was braced in extension enabling progressive flexion over 4 weeks. Anterior knee pain diminished post-operatively and 10 months following surgery the patient was pain free, able to walk normally and scored 99/100 on the Fulkerson modification of the Lysholm score.
