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
Background: People with autism frequently exhibit poor social skills, communication difficulties, and repetitive and stereotyped behaviors. MicroRNAs (miRNAs) are potential and promised targets in developing of new treatment strategies for autism. This study aimed to assess the relative expression of miR-124a, miR-34a-3p, miR-545-3p, miR-153, and BDNF in the blood samples of autistic children. Methods: The children autism rating scale (CARS) was used to determine the severity of autism and to confirm the diagnosis. Blood samples were obtained from 50 patients and 40 age-/sex-matched healthy controls. Expressions of miR-545-3p, miR-34a-3p, miR-124a, and BDNF were evaluated using qRT-PCR. Pearson's correlation coefficient and regression analysis were used to check correlations between relative expressions of the miRNAs and BDNF. Biomarker potencies were assessed by ROC curve analysis. Results: qRT-PCR analysis showed that the relative expressions of miR-545-3p, miR-34a-3p, miR-124a, and BDNF were significantly higher in the patients' group than the healthy controls. However, the relative expression of miR-153 was significantly lower in the case group than the control group. The relative expression of miR-124a was positively correlated with those of miR-545-3p and BDNF among the patients group. Also, the relative expressions of miR-545-3p and BDNF were positively correlated with each other. The ROC curve data also indicated that miR-124a, miR-34a-3p, miR-545-3p, miR-153, and BDNF could be possible diagnostic biomarker for CARS diagnosis (AUC=0.8328, AUC=0.8354, AUC=0.6727, AUC=0.8518 and AUC=0.8214, respectively). Conclusions: Deregulation of miR-124a, miR-454-3p and BDNF might be considered as potential biomarkers for severity of autism.
