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 apoptosis of granulosa cells can result in follicular atresia, a key process in follicle selection and development. The related molecular mechanisms were explored to study the effects of liver receptor homolog-1 (Lrh-1) on apoptosis, sodium-titanium system, and steroid synthesis of granulosa cells from Hu sheep in vitro. After constructing, designing, and synthesizing the Lrh-1 overexpression vector, liposomes were used to transfect Hu sheep granulosa cells. Thereafter, qRT-PCR and Western blot were used to detect the mechanism of Lrh-1 on the titanium system and steroid synthesis of Hu sheep granulosa cells. The overexpression efficiency was determined by fluorescence 48 h after liposome transfection into the Hu sheep granulosa cells in vitro culture. The transfection efficiency was higher, hence providing a basis for subsequent experiments. However, the protein level and transcriptional level of Lrh-1 significantly increased after transfection with Lrh-1 overexpression vector in Hu sheep granulosa cells. We further revealed that after Lrh-1 overexpression in Hu sheep granulosa cells, the expression of the pro-apoptotic gene Bax decreased significantly, while that of the anti-apoptotic gene Bcl-2 increased significantly, as well as the sodium peptide system. Moreover, the expression levels of natriuretic peptide precursor A, B, and C (NPPA, NPPB, NPPC) all showed an upward trend, while the expression levels of steroid synthesis-related genes (P450arom and P450scc) decreased. The above results showed that Lrh-1 overexpression influenced the apoptosis, sodium peptide system, and steroid synthesis.
