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

With the increasing survival rates of cancer patients, the demand for fertility preservation in women has become increasingly prominent. Ovarian tissue cryopreservation and transplantation (OTCT) is an emerging fertility preservation technique that offers a unique advantage over embryo or oocyte cryopreservation, as it does not require ovarian stimulation. This makes it particularly suitable for prepubertal girls requiring urgent gonadotoxic therapy and reproductive-age women who cannot delay cancer treatment. Clinical evidence confirms that OTCT can effectively restore female fertility-especially the potential for natural conception-and restore ovarian endocrine function. The OTCT process involves key steps such as patient evaluation, tissue processing, cryopreservation, and transplantation. The patient's age at cryopreservation, ovarian reserve status, and prior exposure to gonadotoxic therapy significantly influence the outcomes of fertility preserva-tion. Optimal tissue preparation and the choice of cryopreservation method are critical for preserving ovarian tissue viability. During processing, the size of ovarian tissue fragments must be carefully controlled to balance freezing efficiency and post-transplantation viability, with adjustments based on individual patient factors. Slow freezing remains the mainstream clinical method, while vitrification is still considered experimental, with its efficacy and safety under ongoing investigation. The number, size, and transplantation site of ovarian tissue grafts impact their biological activity and functional outcomes. Both orthotopic and heterotopic transplantation can restore endocrine function, but orthotopic sites are superior for restoring fertility. A major safety concern in OTCT is the potential risk of reintroducing malignant or premalignant cells upon reimplantation. Innovative techniques such as
