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

BACKGROUND AND

aimsDespite the known association of hip dysplasia and Charcot Marie Tooth disease (CMT), evidence is limited regarding its exact prevalence. Available studies pre-date genetic confirmation of CMT subtypes and current hip reconstruction surgical options. This study examined the prevalence of hip dysplasia in CMT in a tertiary neuromuscular center.

methodsThis was a retrospective study of children with CMT who had at least one pelvic radiograph between 2000 and 2020. Reimer's migration percentage, acetabular index and lateral center edge angle were used to identify hip dysplasia.

resultsA total of 178 children were included with a median age of 6.4 (IQR 3.4-11.3) years at CMT diagnosis. First pelvic radiographs were performed at a median age of 8.0 (IQR 4.6-12.2) years and 64 (35.8%) had hip dysplasia, of which 20 normalized over time. Repeat radiographs were done in 96/178 children (53.9%), and six children with originally normal radiographs developed later radiographic hip dysplasia. At the time of last follow up, 50/178 children (28.1%) had hip dysplasia and 17/178 children (9.6%) required surgical intervention. The frequency of hip dysplasia in specific CMT subtypes was: 28/100 in CMT1A, 5/7 in Dejerine-Sottas disease, 3/10 in CMT2A, and 4/4 in TRPV4-related CMT.

interpretationThe prevalence of hip dysplasia in children with CMT in this cohort was estimated to be between 9.6% and 28.1%. Serial imaging is important to monitor outcomes into adulthood. Specific CMT subtypes were more likely to be associated with hip dysplasia.
