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

backgroundLegg-Calvé-Perthes disease (LCPD) is an important cause of limping and/or hip pain in preadolescent children.

objectivePathogenesis and epidemiology of LCPD, classification of disease stages, quantitative femoral head involvement and prognosis based on X‑ray images and magnetic resonance imaging (MRI). MATERIAL AND

methodsSummary and discussion of the basic research and recommendations.

resultsBoys between 3 and 10 years of age are mostly affected. The etiology of the femoral head ischemia is still unknown. Commonly used classifications are the stages of disease according to Waldenström and the extent of the femoral head involvement according to Catterall. Head at risk signs are used for early prognosis, and after completion of growth Stulberg's end stages are applied for long-term prognosis.

conclusionBased on X‑ray images and MRI, different classifications can be used for an assessment of progression and prognosis of LCPD. This systematic approach is essential to identify cases that require surgical treatment and to avoid complications such as early onset osteoarthritis of the hip.
