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

Hereditary neuropathy with liability to pressure palsy (HNPP) is associated with a heterozygous 1.5 megabase deletion on chromosome 17 that includes the peripheral myelin protein (PMP) gene PMP22. We show that heterozygous PMP22 knock-out mice, which carry only one functional pmp22 allele and thus genetically mimic HNPP closely, display similar morphological and electrophysiological features as observed in HNPP nerves. As reported previously, focal hypermyelinating structures called tomacula, the pathological hallmarks of HNPP, develop progressively in young PMP22(+/0) mice. By following the fate of tomacula during aging, we demonstrate now that these mutant animals are also interesting models for examining HNPP disease mechanisms. Subtle electrophysiological abnormalities are detected in PMP22(+/0) mice >1 year old, and a significant number of abnormally swollen and degenerating tomacula are present. Thinly myelinated axons and supernumerary Schwann cells forming onion bulbs as fingerprints of repeated cycles of demyelination and remyelination are also encountered frequently. Quantitative analyses using electron microscopy on cross sections and light microscopy on single teased nerve fibers suggest that tomacula are intrinsically unstable structures that are prone to degeneration; however, the severity of morphological and electrophysiological abnormalities in PMP22(+/0) mice is variable. These combined findings are reminiscent of the disease progression in HNPP and offer a possible explanation about why some HNPP patients develop a chronic motor and sensory neuropathy later in life that resembles demyelinating forms of Charcot-Marie-Tooth disease by both morphological and clinical criteria.
