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
The adap1 (ADP-ribosylation factor GTPase-activating protein [ArfGAP] with dual pleckstrin homology [PH] domains 1) gene is predominantly expressed in the mouse brain and is important in neural differentiation and development. However, the functions of adap1 in morphogenesis, locomotor activity, and behaviors in vertebrates are not fully understood. Whole-mount in situ hybridization (WISH) analysis revealed that adap1 was widely expressed in the zebrafish brain, including the forebrain, midbrain, and hindbrain, during early embryogenesis. To investigate the physiological function of the adap1 gene, we generated zebrafish adap1 mutants harboring frameshift mutations around codon 120 of adap1. The adap1 mutants containing homozygous mutant alleles exhibited no apparent morphological abnormalities at 1 day postfertilization (dpf), and the spontaneous coiling and touch response of the adap1 mutants were comparable to those of the wild-type fish. In addition, the expression of neural genes, such as emx1, mbx, and huC, was comparable between the wild-type fish and the adap1 mutants at 1 dpf. The adap1 mutants grew to adulthood without exhibiting any apparent swimming defects. The adult adap1 mutants spent more time than the wild type in the center region of the open field test. In the social behavior test, zebrafish containing the adap1 mutant alleles spent more time than the wild type in the regions near the chambers where novel conspecifics swam. These results imply the involvement of the adap1 gene in regulating approach behavior to visual cues from conspecifics.
