1 · What the graph read from 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.

2 · The registry

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

objectivesWe evaluated the incidence of greater trochanter pain syndrome (GTPS) in patients who underwent magnetic resonance arthrography (MRA) of the hip for a suspected femoroacetabular impingement (FAI) syndrome.

methodsHip MRA performed at our institution (3/2012-1/2014) were reviewed. The absence/presence of FAI (cam, pincer, and mixed) was noted. GTPS diagnosis was based on gluteus medius/minimus tendinopathy/tears, trochanteric bursitis, fascia lata thickening, and trochanter bone oedema/erosion. Subgroup analysis for age (under/over 40 years) and FAI type (cam, pincer, and mixed) was also performed.

resultsN = 189 patients were included (n = 125 males; age 39 ± 12 years). FAI was diagnosed in n = 133 (70, 4%): cam type, n = 85 (63, 9%); pincer type, n = 22 (16, 6%); and mixed type, n = 26 (19, 5%). N = 72 patients (38.1%) had tendinopathy, n = 14 (7.4%) had trochanter erosion, n = 31 (16.4%) had bursitis, n = 4 had bone oedema (2.1%), and n = 3 (1.6%) had fascia lata thickening, resulting in GTPS diagnosis in n = 74 patients (39.2%). The association of normal hip morphology/GTPS was significantly higher (P = 0.023) than that of FAI/GTPS. Under 40 years, GTPS incidence was higher in patients with normal hip and pincer-type FAI (P = 0.028). Over 40 years, no difference between patients with/without FAI (P = 0.119) was seen.

conclusionsGTPS was more frequently observed in patients with normal hip morphology than in patients with FAI, particularly in patients under 40.
