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

purposeSickle cell disease (SCD) is the most common cause of femoral head osteonecrosis (ONFH) during childhood with an overall prevalence of 10%. In children, spontaneous revascularization can occur, as in Legg-Calve-Perthes disease. Consequently, the aim of treatment is to restore proper hip containment to prevent joint arthritis. This is the first study reporting long-term results at skeletal maturity of non-operative and surgical treatments for ONFH in SCD children.

methodsAll children with ONFH due to SCD were retrospectively reviewed. At initial evaluation, extension of osteonecrosis was radiographically defined using Catterall, lateral pillar Herring and Ficat classifications. Subluxation of the femoral head with Reimers migration index > 30% required surgical treatment including femoral varus osteotomy and/or pelvic osteotomies. Conservative treatment including non-weight bearing and physiotherapy was performed in the remaining cases. Outcomes were assessed at skeletal maturity using the Harris Hip Score (HHS) and the Stulberg classification. Total hip arthroplasty and Stulberg 5 were defined as failures.

resultsA total of 25 hips in 17 patients were included (mean follow-up 7.5 years SD 3.4). Mean age at diagnosis was 11.4 years SD 2.9. In all, 15 hips (60%) were classified Catterall 3 and 4 and Herring B and C. A total of 13 patients (52%) underwent surgical treatment. At skeletal maturity, mean HHS was good (81 SD 17), 12 hips (48%) were classified Stulberg 1 and 2, seven hips (28%) were classified Stulberg 3 and 4.

conclusionBoth treatments led to good functional results with 75% of congruent hips at skeletal maturity. LEVEL OF EVIDENCE: IV.
