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

Objective: To report our experiences on the safety of laparoscopic oophorectomy (LO) for ovarian tissue cryopreservation in childhood cancer (CC) patients. Design: Descriptive study of a prospectively registered cohort. Subjects: All CC patients undergoing LO in the Netherlands from November 2020 until April 2024. Exposure: Laparoscopic oophorectomy for means of fertility preservation before or during gonadotoxic treatment. Main Outcome Measures: Safety, including procedure-related complications, such as critical events (desaturation, bradycardia), need for mechanical ventilation in a pediatric intensive care unit (PICU), site infections, hemorrhage, and survival, scored according to Clavien Dindo (CD) classification. Results: Eighty-eight patients, median age 6.5 years (range 1-18 years) underwent LO, of which 2/88 patients developed CD grade 4, 1/88 CD grade 3, and 8/88 CD grade 2 complications, with the most common being port site infection (6%) and bleeding (6%). No clear determinant could be identified as a risk factor for complications. All patients recovered from procedure-related complications and no patient died as a consequence of oophorectomy. Conclusion: Laparoscopic oophorectomy is a relatively safe procedure to preserve future fertility for girls with cancer with a high risk of gonadal failure and consequent infertility. However, LO can be accompanied by complications in children with cancer. Therefore, safety monitoring and identification of risk factors for complications based on larger cohorts in future studies are needed. Prevention of complications of LO is an important obligation to balance the future benefits against the risks of LO to enhance the future chance of pregnancy for girls with cancer.
