Radiographic predictors of femoroacetabular impingement treatment outcomes.
Synthesis in Knee surgery, sports traumatology, arthroscopy : official journal of the ESSKA, 2017. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
purposeTo review the literature on femoroacetabular impingement (FAI) treatment outcomes, specifically focusing on potential pre-operative radiographic parameters that may provide prognostic information regarding outcomes following surgical management.
methodsA comprehensive review of computerized literature databases (Medline Ovid and PubMed) was performed, searching for articles reporting on FAI treatment outcomes. A single reviewer screened titles, abstracts and performed full-text reviews of eligible studies. The references of these studies were further screened for additional potentially relevant studies. A total of 243 studies were reviewed, with 18 meeting inclusion criteria.
resultsThirteen arthroscopic studies reported on 1556 patients, with clinical improvement in 35-92 % of patients and associated failure rates of 12-71 %. Five open surgical studies reported on 238 patients with clinical improvement in 65-95 % of patients and associated failure rates of 0-35 %. Both arthroscopic and open studies identified inferior outcomes with pre-operative radiographic findings of an elevated Tönnis grade (grade 2 or higher), joint space <2 mm, lateral centre-edge angle (LCEA) <20° and incomplete femoral osteoplasty.
conclusionPre-operative radiographic findings of osteoarthritis (Tönnis grade 2/3, <2 mm joint space) or dysplasia (LCEA < 20°) should be considered relative contraindications to joint preservation surgery as outcomes are worse among these patients and associated with a higher risk of conversion to total hip arthroplasty. Care should also be taken to perform a thorough femoral osteoplasty to reduce the risk of failure and need for revision surgery. LEVEL OF EVIDENCE: III.
