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
E200K mutation of the prion protein gene (PRNP) presented with a variety of phenotypes. A 55-year-old woman complaining of slowly progressive walking difficulties came to our observation. She showed a severe progressive ataxo-spastic syndrome but a mild cognitive impairment only. Repeated EEGs showed a diffuse slowing of the rhythm without specificity. Brain MRI revealed by FLAIR showed widespread multiple hyperintensities in the whole cerebral cortex, caudate and putamen nuclei, and in the pulvinar and medial thalamus bilaterally. These signal abnormalities were best detected by DWI with restricted diffusion on ADC map. The clinical diagnosis of possible genetic Creutzfeldt-Jakob disease (CJD) has been confirmed by PRNP gene analysis which revealed the presence of a E200K mutation. This report confirms the heterogeneity of phenotypes in E200K mutated familial CJD with the occurrence of a new phenotype not previously described.
