Imaging diagnosis of upper motor neuron compromising in a patient with Chiari 1 malformation.
Article in BMJ case reports, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
We report a case of a typical MRI from a patient with bulbar-onset sporadic amyotrophic lateral sclerosis associated with Chiari type 1 malformation. Our report reinforces the conventional neuroimaging appearance associated with each condition and the associated abnormalities on a clinical and advanced imaging techniques basis. The MRI signal intensity was useful for detecting upper motor neuron degeneration based on corticospinal tract signal intensity, while diffusion tensor imaging parameters were limited to this purpose. Our description reinforces the relevance of the T1 magnetisation transfer sequence to demonstrate corticospinal tract degeneration and corroborate an amyotrophic lateral sclerosis diagnosis in an individual participant, when there is a potential concurrent 'amyotrophic lateral sclerosis mimic syndrome'. To our knowledge, this is the first description of the non-conventional MR techniques applicability to distinguish the impact of amyotrophic lateral sclerosis from Chiari 1 malformation.
