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
Sperm cryopreservation is an effective fertility preservation method for cancer patients before anticancer treatments. However, there are little data on fertility preservation in large cohorts of patients with cancer in southern China. This retrospective cross-sectional study aimed to assess the fertility preservation status of 1034 newly diagnosed male patients with cancer in the Human Sperm Bank of Guangdong Province in southern China (Guangzhou, China). Of these, 302 patients had reproductive system tumors, mostly testicular cancers (99.0%), and 732 had other tumors, including lymphoma (33.1%), gastrointestinal cancer (16.3%), nasopharyngeal carcinoma (15.7%), leukemia (7.7%), sarcoma (3.6%), and others (23.6%). Patients with reproductive system tumors had lower sperm concentration and prefreezing and post-thawing progressive motility than those with non-reproductive system tumors (all P < 0.001). Differences in sperm concentration, progressive motility, and normal morphology rate were observed between patients with and without anticancer surgery before sperm cryopreservation (all P < 0.05). As of April 30, 2022, 63 patients used their cryopreserved sperm for assisted reproductive technology treatments and 39 pregnancies were achieved. This study provides valuable data on the fertility preservation status in newly diagnosed cancer patients in southern China, demonstrating that patients with reproductive system tumors had poor sperm quality for their pretreatment fertility preservation.
