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
Ovarian tissue cryopreservation has been gradually applied. It is essential to elucidate the differences between cryopreserved and fresh ovarian tissue and to refine cryopreservation protocols for improved outcomes. To explore the transcriptomic differences between fresh ovarian tissue and tissue cryopreserved with an elevated thawing rate. Ovarian tissue samples were collected and cryopreserved (frozen and thawed) following RNA sequencing and histological evaluation. Three groups were formed: fresh tissue (Group 1), frozen tissue after quick thawing at 100 °C (Group 2), and frozen tissue after slow thawing at 37 °C (Group 3). KEGG analysis showed that in comparison with Group 1, DEGs in Group 2 were mainly enriched in the cortisol synthesis and ovarian steroidogenesis pathways, and DEGs in the cells of Group 3 were mainly enriched in the ovarian steroidogenesis pathway. GO analysis showed that compared to cells of Group 2, DEGs in Group 3 were primarily enriched in the SRP-dependent co-translational protein targeting pathway and co-translational protein targeting to the membrane. The results were formulated with a minimal difference in the histological evaluation of cells after quick and slow thawed tissue. Cryopreservation of ovarian tissue by the described method does not decrease follicle production but downregulates the ovarian steroidogenesis pathway, reducing estrogen and progesterone secretion. The quick thawing of ovarian tissue increases the proliferation and apoptosis pathways of cells.
