Neurophysiological characteristics of cognitive functions in patients with first episodes of endogenous psychosis.

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
This report presents studies of the neurophysiological correlates of the characteristics of cognitive disorders in patients with first psychotic episodes of endogenous psychosis at juvenile age. Three groups of patients were studied: those with a predominance of catatonic symptomatology (22 patients), those with a predominance of hallucinatory-delusional symptomatology (22 patients), and those with a predominance of affective-delusional symptomatology (24 patients), along with a group of psychologically healthy subjects (15 subjects). Parameters of auditory evoked potentials were analyzed using the oddball paradigm. The group with a predominance of catatonic disorders showed the greatest differences in the latent periods (LP) of the N200 and P300 components as compared with the other groups; patients with a predominance of hallucinatory-delusional symptomatology showed the most localized anomalies in the latent period of the P300 component; the group of patients dominated by affective-delusional symptomatology showed almost no increase in the latent period of the N200 component, though the extents of anomalies in the N100 component in responses to non-target signals and deviations in the P300 component were more marked than in the other groups. These characteristics of the neurophysiological correlates of cognitive functions in each group of patients supported the significance of evaluating the psychopathological structure of manifest psychotic episodes for determining the clinical typology.
