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

Introduction: For metachronous bilateral testicular tumors occurring in young adulthood, the post-treatment quality of life must be considered when making treatment decisions. Case Presentation: A 46-year-old man presented to our hospital with a chief complaint of two bean-sized hard masses palpable in the right testis. At the age of 35, he had undergone inguinal orchiectomy for a tumor in the left testis, and the histopathological diagnosis was seminoma, with the stage pT1, N0, M0, S0. Adjuvant chemotherapy with carboplatin was not administered postoperatively. To preserve fertility, testis-sparing surgery was performed. The warm ischemic time during surgery was 32 min. Histopathological examination indicated seminoma, and biopsy did not reveal germ cell neoplasia in situ. His sexual function was preserved at 22 months after surgery; however, semen analysis revealed azoospermia. Conclusion: Testis-sparing surgery should be considered for metachronous bilateral testicular tumors, particularly for patients with tumor onset in young adulthood as it was thought to have the potential to maintain a favorable prognosis and fertility.
