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

backgroundBoth patients with methamphetamine-associated psychosis (MAP) and patients with schizophrenia suffer from obvious cognitive deficits in working memory, and this affects the functional prognosis of patients.

aimThis study is to investigate the difference of working memory deficits between patients with MAP and patients with schizophrenia, especially the difference of central executive system function, and the relevance of working memory deficits and clinical characteristics.

methodsTwenty-eight male patients with MAP and twenty-eight patients with schizophrenia were recruited. The working memory of subjects was evaluated with the n-back task edited and adapted from English language materials. The positive syndrome scale of PANSS and CGI were employed to assess psychotic symptoms and the severity of patients.

resultsAccording to the results of repeated measure variance analysis, it was found that both the between-group variable (group) and within-group variable (n) had significant main effects, and the interaction between the between-group variable and the within-group variable was also significant. After Z-transformation, mean (sd) working memory scores of patients with MAP and schizophrenia were 0.91 (0.77) and -0.91 (2.11) respectively, and the difference between these two groups were statistically significant (

conclusionPatients with MAP were better at regulating, updating, executing and controlling active information than patients with schizophrenia.
