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
purposeInsomnia is a major public health concern that often occurs in patients with schizophrenia, complicating the treatment and prognosis of patients. This study aimed to investigate the prevalence of insomnia and its relationship with cognitive function in Chinese patients with chronic schizophrenia.
methodsWe recruited patients with schizophrenia and collected their clinical and demographic data. Insomnia data were collected through a self-reported questionnaire consisting of three questions. The positive and negative syndrome scale (PANSS) was used to measure psychopathological symptoms, while the repeatable battery for the assessment of neuropsychological status (RBANS) was used to measure cognitive performance.
resultsOf 957 Chinese patients with chronic schizophrenia 20.2% reported having insomnia (193/957). Male patients (107/630, 17.0%) had a lower rate of insomnia than female patients (86/327, 26.3%) (x
conclusionsInsomnia is relatively common in Chinese patients with chronic schizophrenia. Some demographic data and clinical symptoms are associated with insomnia. Patients with schizophrenia and insomnia perform poorly on cognition tests suggesting that insomnia and cognitive function are closely related in patients with schizophrenia.
