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
Sex is an important biological variable as many physiological as well as disease processes differ between females and males. The fundamental biological distinction between females and males starts with chromosomal sex, and the establishment of XX and XY cells and tissues. Polymerase Chain Reaction (PCR) is a simple and effective method to easily determine chromosomal or genetic sex of cells and tissues. The goal of this study was to develop a simple multiplex PCR genotyping assay to distinguish XX and XY tissues in sheep. Primers were designed to amplify a fragment of the autosomal gene myogenin (MYOG) and sex determining region on the Y chromosome (SRY). PCR analysis was performed on a variety of genomic DNA samples isolated from fetal sheep skeletal muscle, brain, liver, and placenta, and revealed a single 259 bp band for MYOG in XX females, and a 259 bp band for MYOG and a 167 bp band for SRY in XY males. Amplicons were clearly distinguishable by gel electrophoresis, and their sequences revealed 100% identity to the known ovine MYOG and SRY sequence. The reported multiplex PCR genotyping assay provides a rapid means to distinguish XX and XY sheep tissues using low volume samples.
