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

X linked hypophosphataemia (XLH) is a rare condition with numerous musculoskeletal complications. It may mimic other more familiar conditions, such as vitamin D deficiency, ankylosing spondylitis or diffuse idiopathic skeletal hyperostosis. We describe two cases with Chiari type 1 malformations and syringomyelia, neither of which is well recognised in XLH. The first presented late with the additional complications of spinal cord compression, pseudofracture, renal stones and gross femoroacetabular impingement requiring hip replacement. The second also had bulbar palsy; the first case to be described in this condition, to the best of our knowledge. We wish to raise awareness of the important neurological complications of syringomyelia, Chiari malformation, spinal cord compression and bulbar palsy when treating these patients. We also wish to draw attention to the utility of family history and genetic testing when making the diagnosis of this rare but potentially treatable condition.
