[Clinical and neurophysiological patterns of early presenting symptoms in acute onset chronic inflammatory demyelinating polyradiculoneuropathy].
Article in Revista de neurologia, 2022. 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
introductionThe phenotypes of chronic inflammatory demyelinating polyneuropathy (CIDP) include an acute-onset phenotype (A-CIDP) with an evolution time of less than eight weeks from the onset of symptoms. This entity can be confused with Guillain-Barre syndrome of the acute inflammatory demyelinating variety (AIDP), delaying the start of treatment.
objectiveTo analyze the clinical and electrophysiological differences between A-CIDP, classic CIDP and AIDP, in order to identify factors that may help in the early differential diagnosis. PATIENTS AND
methodsA cross-sectional study was carried out with patients seen at the neuromuscular disease clinic of the National Institute of Neurology and Neurosurgery with a diagnosis of CIDP according to the criteria of the European Federation of Neurological Societies and Peripheral Nerve Society. Patients with CIDP <8 weeks were categorized as A-CIDP and were compared with patients diagnosed with classic CIDP and AIDP. Clinical, paraclinical and electrophysiological variables were obtained and analyzed.
resultsSignificant differences in history of infection, cranial nerve involvement and dysautonomia were observed between A-CIDP and AIDP. Electrophysiological recordings reported significant differences in motor nerve conduction velocity and sural nerve recordings, being lower in the A-CIDP group.
conclusionA history of infection, cranial nerve involvement and dysautonomia are important parameters to take into account for the differential diagnosis of these entities. Electrophysiological analysis is similar between A-CIDP and CIDP. The differential diagnosis between these types of demyelinating polyneuropathy must be based on clinical assessment.
