1 · What the graph read from it

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.

2 · The registry

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

Advances in early cancer diagnosis and treatment have significantly improved survival rates. However, as awareness grows about the adverse effects of cytotoxic therapies on ovarian function and fertility, an increasing number of patients are seeking fertility preservation before undergoing anti-cancer treatments. Embryo cryopreservation remains the gold standard for fertility preservation when there is sufficient time for ovarian stimulation and oocyte retrieval. For single women, oocyte freezing offers a viable alternative, allowing them to preserve their eggs for future use. For prepubertal girls and women who cannot delay treatment, ovarian tissue cryopreservation is currently the only feasible method of fertility preservation. Between 2000 to 2010, researchers at Royan Institute conducted a wide range of investigations on ovarian tissue cryopreservation, providing a structured and evidence-based fertility preservation protocol for cancer patients candidates for this service. In 2010, the Royan Institute established the Royan Human Ovarian Tissue Bank (OTB) as a subgroup of the Embryology Department. After obtaining ISO 9001:2015 certification, the OTB was officially transferred to the Royan Infertility Clinic. This article presents the Royan OTB guidelines for cryopreserving ovarian tissue in prepubertal girls and women with cancer, described step by step.
