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

Background: Spermatocytic tumor is a rare type of testicular germ cell tumor, accounting for approximately 1% of all testicular neoplasms. Case Presentation: A 51-year-old male presented to the hospital with a painless mass in the left testis. Ultrasonography revealed a heterogeneous intratesticular mass with cystic components. Testicular tumor markers were within normal ranges. The patient underwent a left orchiectomy. Pathologically, the tumor was characterized by the presence of medium to large neoplastic cells and small neoplastic cells without sarcomatoid or anaplastic features. Immunohistochemically, the tumor was positive for SALL4 and negative for CD30, AFP, OCT3/4, PLAP, D2-40, and hCG. Based on these findings, we diagnosed spermatocytic tumor of testis. Conclusion: We present a case of spermatocytic tumor, which is a distinct entity among testicular germ cell tumors, with a generally favorable prognosis following orchiectomy. However, long-term follow-up is recommended due to the potential for late metastasis.
