High prevalence of gonadal dysfunction in pediatric sarcoma survivors: insights from hormonal and clinical markers.
Article in Frontiers in pediatrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: A critical proportion of childhood bone and soft tissue sarcoma survivors experience some form of reproductive impairment. These findings underscore the increasing need for a comprehensive evaluation of gonadal function in this patient population. This study aimed to evaluate gonadal function in survivors of childhood bone and soft tissue sarcomas and to identify treatment-related risk factors. Methods: This retrospective cohort study included survivors aged 17 years or older at evaluation who had received curative-intent treatment for bone or soft tissue sarcomas diagnosed between January 2009 and February 2022. Demographics, clinical history, hormonal assays [follicle-stimulating hormone (FSH), luteinizing hormone, anti-Müllerian hormone (AMH), inhibin B, estradiol, testosterone], pelvic ultrasonography (females), and semen analysis (males) were recorded. Results: The cohort comprised 38 participants (median age 18.75 years); 17 males (44.74%) and 21 females (55.26%). Gonadal dysfunction was observed in 18 participants (47.4%), including low ovarian reserve or diminished AMH as the most common finding in females and azoospermia as the most frequent abnormality in males. Normal gonadal function was preserved in 20 participants (52.6%). FSH levels were significantly higher in the gonadal dysfunction group in both females ( Discussion: Childhood sarcoma survivors have a high prevalence of gonadal dysfunction, with notable impairments in ovarian reserve and spermatogenesis, marked by elevated FSH in both sexes. Routine surveillance, patient education on gonadotoxicity and infertility risks, and pre-treatment fertility preservation counseling are essential.
