Predictors of Surgery and Cost of Care Associated with Patellar Instability in the Pediatric and Young Adult Population.
Article in Arthroscopy, sports medicine, and rehabilitation, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
purposeTo determine how patient demographics, socioeconomic status, history of recurrence, and initial point of presentation for health care influenced the decision for surgical treatment following a patellar instability episode.
methodsThe New York SPARCS database from 2016 to 2018 was queried for patients aged 21 and younger who were diagnosed with a patellar instability episode. These were linked to later surgeries with Current Procedural Terminology (CPT) codes 27405 (MPFL repair), 27418 (tibial tubercle osteotomy), 27420 (dislocating patella reconstruction), 27422 (Campbell/Roux-Goldthwait procedure), and 27427 (extra-articular knee ligamentous reconstruction). χ
resultsThere were 2,557 patients with patellar instability, 134 (5.2%) of whom underwent surgery. Patients with recurrent instability had 1.875 times higher odds of undergoing surgery (
conclusionsPatients with recurrent instability had higher odds of surgery, while Black and uninsured patients had lower odds of surgery. ED visits were associated with significantly higher charges compared to office visits, and Black patients had higher charges than white patients. Minority and uninsured patients may face barriers in access to orthopedic care. LEVEL OF EVIDENCE: Level III, retrospective cohort study.
