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

backgroundTesticular malakoplakia (MP) is an extremely rare chronic granulomatous inflammatory lesion. It lacks specific clinical or imaging features and is highly prone to misdiagnosis as a testicular tumor. To our knowledge, no reports have described the contrast-enhanced ultrasound (CEUS) manifestations of this condition. Herein, we present a case with the aim of improving the understanding of testicular MP and reducing unnecessary misdiagnosis and oversight. PATIENT PRESENTATION: A 41-year-old Han Chinese male presented with unexplained right scrotal swelling for more than 20 days, accompanied by intermittent fever, chills, and dysuria, along with mild distending pain in the enlarged testicle. CEUS revealed that the right affected testicle had rapid high enhancement and slow washout. Computed tomography (CT) and magnetic resonance imaging (MRI) showed marked enlargement of the right testicle and altered parenchymal density, suggestive of a neoplastic lesion. Urine culture confirmed a bacterial infection with Escherichia coli (E. coli). Treatment with ceftriaxone and other antimicrobial agents yielded no significant improvement. Subsequently, a right orchiectomy was performed, and pathological examination confirmed the diagnosis of testicular MP. The patient's urinary symptoms gradually resolved postoperatively. During the 3-month follow-up, no recurrence was observed, and inflammatory markers remained within the normal range.

conclusionsThe clinical and imaging presentations of testicular MP are nonspecific, posing a significant challenge for preoperative diagnosis. Definitive diagnosis still relies on pathological examination. Therefore, clinicians should increase their awareness of this rare disease to avoid misdiagnosis. To our knowledge, this report represents the first description and analysis of CEUS manifestations in a case of testicular MP.
