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
introductionAmyotrophic Lateral Sclerosis (ALS) affects upper (UMN) and lower (LMN) motor neurons. ALS diagnosis is challenging, especially in predominant LMN phenotypes. Electromyography can disclose LMN damage, while UMN involvement is detectable by clinical examination, with possible support of magnetic resonance imaging (MRI) and transcranial magnetic stimulation. Our aim was to investigate the role of 2-[
methodsIn our cross-sectional study, we created an UMN burden score. Performing a multiple regression analysis in SPM12, we evaluated the relationship between UMNBS and brain metabolism. We split ALS cohort based on the UMN burden score median value (group A-under median, group B-above median). We ran a full factorial analysis including group A and B and healthy controls, followed by group comparisons.
resultsWe included 118 ALS patients (group A and B, N = 59), with a median UMN burden score of 9.50 and a left lateralization of UMN signs. We found a negative correlation between motor cortex metabolism and UMN burden score. Comparing each ALS group with healthy controls, we found relative hypometabolism in the left frontal lobe and relative bilateral, right-prevalent hypermetabolism of cerebellum and corticospinal tracts. The relative hypermetabolism in corticospinal tracts was more evident in the group with low UMN signs.
conclusionsMotor cortex metabolism reflects UMN burden. Corticospinal tracts' metabolic changes could provide information about UMN involvement even in patients with predominant LMN phenotype, suggesting a possible role of brain 2-[
