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

Charcot-Marie-Tooth 1A disease (CMT1A) is a disease for which no drug treatments are available. In 2004, it was reported that ascorbic acid reduced the severity of neuropathy in transgenic mice overexpressing PMP22, an animal model of human CMT1A, compared with untreated mice. Based on those results, clinical trials were undertaken at different centers worldwide and four of them have been completed, but none of them resulted in significant improvements. Based on the pharmacokinetics of ascorbic acid, we propose that the randomized clinical trial carried out thus far confirmed the tight control of ascorbic acid's absorption and proved its tolerability at one and two years. The pharmacokinetic considerations discussed in this article might largely explain the disappointing results of the recent CMT1A trials.
