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

objectiveTo describe magnetic resonance imaging (MRI) findings in professional soccer players with acute apophyseal injury of the hip and to assess their relationship with return to sports. MATERIAL AND

methodsAdolescent soccer players with diagnosis of apophyseal injury in the anterosuperior and anteroinferior iliac spine were retrospectively evaluated between 2008 and 2016. All athletes underwent hip MRI examination within 4 days after onset of clinical complaint. Images were independently analyzed by two radiologists. Medical records were reviewed to obtain clinical data.

resultsMean displacement of the apophysis was 4.8 ± 4.6 mm. Bone edema was present in 82% of athletes and muscular edema in 41%. The mean time to return to sports was 37.3 ± 14.7 days. The difference between the measurements of the two radiologists was close to zero with agreement limits below 1.0 mm (p < 0.001). There was a significant correlation between displacement of the apophysis and return to sports, as well as between both and the presence of muscular edema. A displacement of the apophysis of 3.0 mm might serve as a parameter to predict return to sports/activity before 40 days, with a sensitivity of 92% and specificity of 96%, considering conservative physiotherapy treatment.

conclusionDisplacement of the apophysis and presence of muscular edema evaluated by MRI showed a significant correlation with return to sports in athletes with acute apophyseal injuries of the anterosuperior and anteroinferior iliac spines.
