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

Background: There are several hypotheses on what causes schizophrenia, some of which include inflammatory responses. Additionally, it might be challenging to control and treat cognitive abnormalities, which represent the primary symptoms, and may be related to inflammation. This study aims to determine whether there is a relationship between C-reactive protein levels and cognitive abilities by assessing neuropsychological tests of drug-free patients with schizophrenia and first-episode psychosis. Methods: The patient group consisted of 36 patients with schizophrenia or "first-episode psychosis," while the control group comprised 31 healthy people. The control group consisted of healthy participants without any medical or psychiatric diseases. Structured Clinical Interview for DSM-5 axis I disorders was applied for diagnosis, while Wisconsin card sorting test, Stroop color and word test, trail making tests, Rey auditory verbal learning test, and digit span test were applied for cognitive assessment of both groups. Clinical characteristics of patients were evaluated by using the Scale for the Assessment of Positive Symptoms, the Scale for the Assessment of Negative Symptoms, and the Calgary Depression Scale for Schizophrenia. The patient group and healthy control group were evaluated in terms of inflammation levels. The C-reactive protein levels were measured, and their relationship with cognitive status was examined. The serum samples were analyzed by the immunoturbidimetric method in C-reactive protein C8000 Architect (Abbott, Ill, USA) to measure the C-reactive protein levels. Results: C-reactive protein levels were found to be higher in the patient group ( Conclusion: Elevated peripheral levels of C-reactive protein are associated with poorer cognitive function in patients with first-episode psychosis and schizophrenia, particularly, complex attention associated with the Stroop test. Inflammation may have an impact on cognitive impairment in psychosis.
