Prevalence of femoro-acetabular impingement in non-arthritic patients with hip pain: a meta-analysis.
Synthesis in International orthopaedics, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 14 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
purposeAs the prevalence of femoro-acetabular impingement syndrome (FAIS) in symptomatic patients who lack evidence of hip osteoarthritis (OA) remains to be described, the purpose of this study was to calculate the prevalence of FAIS in this patient population.
methodsLibraries of PubMed, Embase, and Ovid were systematically reviewed for all studies between 2009 and 2019, investigating femoro-acetabular impingement and hip pain. Level I-IV studies delineating patients with hip pain who do not have OA (Tonnis or Outerbridge grades < three) were included. Demographics, outcomes, radiographic parameters, and criteria were entered into a meta-analysis to calculate the incidence of FAIS in non-arthritic symptomatic hips.
resultsIn total, 2264 patients (2758 hips) were included in the pooled analysis. Weighted mean age was 31 years. The incidence of FAIS in patients with no evidence of osteoarthritis but who complain of hip pain is 61% (47.3-74.4%). In total, 1483 hips were diagnosed with FAIS. Of the studies that described the rates of all three of the various subtypes of FAIS in their reports, 37% had a combined-type, 38% had a cam-type, and 25% had a pincer-type FAIS.
conclusionFemoroacetabular impingement should be suspected in 47 to 74% of patients with hip pain and without arthritis. Physicians must maintain a high index of suspicion for FAIS in young patients presenting with hip pain, as FAIS is a common and treatable condition that, if left alone, may lead to hip degeneration.
