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
backgroundWe investigated the applicability of human decellularized ovarian scaffold (HDOS) to create an artificial ovary for preserving germ cells and forming follicular-like structures in a mouse chemotherapy-induced premature ovarian failure (chemo-POF) model after seeding stromal cells and transplantation.
methodsThe present study was conducted in three steps. (1) Creation of a mouse POF model, (2) Production of an artificial ovary (AO), (3) Transplantation of AO to ovariectomized mice. For the first step, female NMRI mice received chemotherapy drugs to induce POF. For AO production, mouse ovarian cell suspension (OCS) from the POF model and the control group were isolated separately and seeded into human decellularized ovarian scaffolds (HDOSs). AO was transplanted to ovariectomized intact and POF mice, which were followed up for 2 months (AOII). After transplantation, histological assessments, hormonal evaluation (FSH/E2), and gene expression analysis were conducted (Blimp1).
resultsA follicle-like structure formed two months after the transplantation. No significant increase was observed in the FSH level in both the Intact/AOII and POF/AOII groups. The gene expression of Blimp1 showed a significant increase in the Intact/AOII group compared to the other groups.
conclusionsThe bioengineered ovary is capable of forming a follicle-like structure in the POF model after cell seeding and transplantation. We also demonstrated the efficacy of these extracellular matrices (ECMs) in preserving germ cells.
