The neurodevelopmental basis of schizophrenia: clinical clues from craniofacial dysmorphology in northwest Ethiopia, 2020.

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
backgroundThe neurodevelopmental speculation of schizophrenia states that the pathogenesis of schizophrenia starts with early fetal or neonatal neurocraniofacial development rather than youthful adulthood when manic signs and symptoms are evident. However, there is no direct evidence of a pre-or peri-natal lesion associated with schizophrenia, rather indirect evidence of impaired development can be seen in macroscopic anatomical variations as well as microscopic immunohistochemical anomalies. One approach to studying neurodevelopmental disturbances among schizophrenic patients is somatic physical evidence or neurodevelopmental markers. Thus Our study aimed to assess the neurodevelopmental basis of schizophrenia clinical clues from anthropometric assessment of craniofacial dysmorphology among schizophrenic patients in North West Ethiopia 2019-2020.
methodInstitutional-based comparative cross-sectional study design was conducted in Debre Markos comprehensive specialized hospitals in 190 schizophrenic patients, 190 1st-degree relatives, and 190 healthy controls. Data were collected using standard methods, entered into EpiData version 3.1, and exports to SPSS version 24 for analysis. Descriptive data were analyzed using descriptive statistics. Welch ANOVA and post hoc comparison, a Games-Howell test, were conducted. Significance was set at a p-value of α = 0.05. Read back analysis was also conducted for the conclusion.
resultsFive hundred seventy study samples, male 375(65.8%), and female 195 (34.2%), were included in this study. The Games-Howell test revealed that the coronal arc length and sagittal arc length among schizophrenic patients were statistically significantly longer than the healthy controls (p < 0.006; p < 0.001, respectively). However, the difference between schizophrenic and healthy control regarding head circumference was marginally significant (p = 0.056). Schizophrenic patients had a significantly shorter total facial height (p < 0.001) and upper facial height (p < 0.001) than healthy controls. Regarding facial depth, schizophrenic patients had significantly shallow upper facial depth (p < 0.001), middle facial depth (p = 0.046), and lower facial depth (p < 0.001).
conclusionour finding indicated indirect evidence for disturbed craniofacial development in schizophrenia patients, and close and read back analysis of the result supported the neurodevelopmental basis of disease.
