TGFß Gene Members and Their Regulatory Factors in Granulosa Compared to Cumulus Cells in PCOS: A Case-Control Study.
Article in Cell journal, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
objectiveTransforming growth factor-beta (TGF-β) superfamily and its members that include bone morphogenetic protein 15 (BMP15), anti-Mullerian hormone (AMH), growth /differentiation factor-9 (GDF9), and their respective receptors: BMPR1A, BMPR1B, and BMPR2 have been implicated as key regulators in various aspects of ovarian function. The abnormal function of the ovaries is one of the main contributing factors to polycystic ovarian syndrome (PCOS), so this study aimed to investigate the mRNA expression profile of these factors in granulosa (GCs) and cumulus cells (CCs) of those patients. MATERIALS AND
methodsThe case-control research was conducted on 30 women (15 infertile PCOS and 15 normo-ovulatory patients, 22≤age ≤38 years old) who underwent ovarian stimulation for in vitro fertilization (IVF)/ intracytoplasmic sperm injection (ICSI) cycle. GCs/CCs were obtained during ovarian puncture. The expression analysis of the aforementioned genes was quantified using real-time polymerase chain reaction (PCR).
resultsAMH and BMPR1A expression levels were significantly increased in GCs of PCOS compared to the control group. In contrast, GDF9, BMP15, BMPR1B, and BMPR2 expressions were decreased. PCOS' CC showed the same expression patterns. GDF9 and AMH were effectively expressed in normal CCs, and BMP15 and BMPR1B in normal GCs (P<0.05).
conclusionDifferential gene expression levels of AMH and its regulatory factors and their primary receptors were detected in granulosa and cumulus cells in PCOS women. Since the same antagonist protocol for ovarian stimulation was used in both PCOS and control groups, the results were independent of the protocols. This diversity in gene expression pattern may contribute to downstream pathways alteration of these genes, which are involved in oocyte competence and maturation.
