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

A 22-year-old female suffering from MuSK-myasthenia gravis presented with fatigable eyelid ptosis, fluctuated bulbar symptoms and bilateral eyelid twichings which were greatly reinforced after tight closure of eyes and contraction of orbicularis oculi muscles. The patient never received acetylcholinesterase inhibitor treatment. Persistent twichings, irrespectively of clinical status, were signs of cholinergic hyperactivity. MuSK antibodies disrupt MuSK-collagen Q interaction with resultant deficient binding of acetylcholinesterase at synaptic cleft and impaired breakdown of acetylcholine. In myasthenia gravis, clinical signs of cholinergic hyperactivity may point to seropositivity of MuSK antibodies with therapeutic implications in clinical practice.
