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
objectiveThe expression and distribution of a subtype of purine receptors (P2Y2) in the terminal rectum of fetal rats with anorectal malformations (ARM) were examined to investigate their possible impact on the development of the enteric nervous system (ENS).
methodsPregnant Sprague-Dawley rats were randomly divided into a control group (5 rats) and an experimental group (20 rats). The experimental group was treated with ethylene thiourea (ETU). On gestational day 20, the intrauterine fetal rats were collected from both groups of pregnant rats. Sagittal sections of the pelvic perinea were stained with HE. P2Y2 protein and mRNA expression in the terminal recta of the fetal rats in the control group, the ARM group, and the ETU-treated group that exhibited no malformations (the ETU group) were detected by immunohistochemistry, western blot, and qRT-PCR.
resultsThe fetal rats in the control group showed normal position of the anal opening, with no malformation. The incidence of ARM was 89.2% for the fetal rats in the experimental group. The immunohistochemistry results showed that P2Y2 was expressed in the cytoplasm of the cells in the terminal rectum submucosa and myenteric plexus of the fetus rats in the control group, the ETU group, and the ARM group. The average integrated optical density (IOD) value for the ARM group was significantly lower than the IOD value for the control and ETU groups (186.48 ± 23.03 vs. 493.18 ± 19.70; 186.48 ± 23.03 vs. 479.48 ± 41.71, P<0.01), while the IOD value for the ETU group was comparable to the control group IOD (493.18 ± 19.70 vs. 479.48 ± 41.71, P = 0.360). The western blot and qRT-PCR results showed that the P2Y2 protein and mRNA expressions were significantly lower in the terminal rectum of the fetal rats in the ARM group than in the control and ETU groups (0.28 ± 0.08 vs. 0.51 ± 0.10, 0.28 ± 0.08 vs. 0.48 ± 0.12; 48.91 ± 12.17 vs. 98.03 ± 15.68, 48.91 ± 12.17 vs. 92.53 ± 10.43; P<0.01), while the P2Y2 protein and mRNA levels in the control group were comparable to the ETU group (0.51 ± 0.10 vs. 0.48 ± 0.12, P = 0.494; 98.03 ± 15.68 vs. 92.53 ± 10.43, P = 0.058).
conclusionP2Y2 may participate in and affect the development of ENS in the terminal rectum of fetal rats with ARM.
