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

Using diffusion tensor (DT) magnetic resonance imaging (MRI), damage to brain intrahemispheric and interhemispheric connections was assessed in 26 sporadic primary lateral sclerosis (PLS) patients compared with 28 sporadic amyotrophic lateral sclerosis (ALS) patients with similar disability and 35 healthy controls. DT MRI diagnostic accuracy in distinguishing the two motor neuron disease (MND) variants was tested. PLS and ALS patients showed a distributed pattern of abnormalities of the motor system, including the corticospinal tracts and corpus callosum (CC). PLS versus ALS patients showed a more severe damage to the motor CC fibers and subcortical white matter (WM) underlying the primary motor cortices. Both patient groups showed an extra-motor damage, which was more severe in PLS. This did not appear to be driven by longer disease duration in PLS. In PLS patients, damage to the CC mid-body correlated with the severity of upper motor neuron clinical burden. CC fractional anisotropy values had the highest accuracy in distinguishing PLS from controls and ALS. PLS and ALS share an overlapped pattern of WM abnormalities. This underscores that PLS, despite its distinct clinical phenotype and long survival, still lies within the wider MND spectrum. Whether CC diffusivity may be a novel marker to increase confidence in an early diagnostic separation of PLS from ALS still needs to be investigated.
