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

Pompe disease (PD) is a neuromuscular disorder caused by a mutation in the acid alpha-glucosidase (GAA) gene. Patients with late-onset PD retain some GAA activity and present symptoms later in life, with fatality mainly associated with respiratory failure. This case study presents diaphragm electrophysiology and a histological analysis of the brainstem, spinal cord, and diaphragm, from a male PD patient diagnosed with late-onset PD at age 35. The patient was wheelchair dependent by age 38, required nocturnal ventilation at age 40, 24-h noninvasive ventilation by age 43, and passed away from respiratory failure at age 54. Diaphragm electromyography recorded using indwelling "pacing" wires showed asynchronous bursting between the left and right diaphragm during brief periods of independent breathing. The synchrony declined over a 4-yr period preceding respiratory failure. Histological assessment indicated motoneuron atrophy in the medulla and rostral spinal cord.
