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 aim of the present study was to explore the mechanism of agonists in regulating transcriptional level of polymeric immunoglobulin receptor (pIgR) in salivary gland epithelial cells, thus revealing the defense effect of salivary immune on bacteria in the oral cavity. Sixty patients with oral bacterial infection and 70 patients suffering from oral diseases without bacterial infection were selected randomly from patients in Renmin Hospital of Wuhan University from April 2015 to April 2017. Ribonucleic acid (RNA) was extracted from salivary gland epithelial cells of all patients. Fluorescent quantitative polymerase chain reaction (FQ-PCR) and western blotting methods were adopted to detect and compare the transcriptional level of pIgR. The salivary gland epithelial cells of the 60 patients with oral bacterial infection were isolated and extracted, and they were divided into two groups (observation group and control group) randomly. Agonists were added to the observation group for acting for 24 h. FQ-PCR and immunofluorescence (IF) were adopted to detect and compare the transcriptional level of pIgR after acting with agonists. The toxicity of agonists on the cells was detected with Cell Counting kit-8 (CCK-8). The isolated salivary gland epithelial cells conformed to the morphology of epithelial cells, and adhered to the wall for growing. The transcriptional level of pIgR in the bacterial infection group was lower than that in the non-bacterial infection group (p<0.05). The transcriptional level of pIgR in the observation group was higher than that in the control group (p<0.05) after acting with agonists. Agonists can promote the rise of transcriptional level of pIgR in salivary gland epithelial cells, and the increase in pIgR is closely related to the cure of oral bacterial infection. Therefore, agonists can improve the oral immune function by regulating the transcription of pIgR.
