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

introductionSports participation in children with hemophilia is generally considered to be associated with increased injury risk, which is generally considered highest in severe hemophilia.

aimTo assess sports participation according to age and severity in children with hemophilia and its association with sports injuries.

methodsIn a retrospective single-center study, sports participation, injuries, and bleeding data from three consecutive annual clinic visits were collected for young patients with hemophilia (PWH, aged 6-18). Sports in categories 2.5 and 3 of 3 according to the National Hemophilia Foundation classification were considered high-risk. Groups were compared using chi-square testing.

results105 PWH (median age: 13(IQR 10-14); 53% severe; bleeding rate: 1/y) were identified; three were unable to perform sports and were excluded. The majority of PWH (77%) played sports weekly, of which 80% high-risk sports. Sports participation (median 3.0x/wk), and the proportion of injured PWH was similar in severe (42%) and non-severe (33%) PWH. Sports injuries were rare (65% no injuries in 3 years, median 0/y (IQR 0-1)). Annually, PWH did not report more injuries (15%) than age-matched boys (28%). Sports injuries were not associated with frequency and type of sports. DISCUSSION: This retrospective study showed high sports participation (including high-risk sports) and low injury rates. Sports participation was similar across severities and injury rates were not higher than among the general population. Injuries were not associated with frequency or type of sports. A prospective study with objective assessment of sports participation and injuries is warranted to confirm these findings and avoid recall bias.
