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

objectiveTo investigate the clinical characteristics, diagnostic approaches, treatment strategies, and short-term outcomes of neonatal epididymitis.

methodsA retrospective study was conducted of neonates diagnosed with epididymitis at a tertiary referral center between August 2009 and October 2024. Demographic characteristics, clinical manifestations, imaging findings, microbiological results, treatment, and follow-up outcomes were analyzed.

resultsThirty neonates were included. The median gestational age was 39 weeks (IQR, 38.00-40.00 weeks), and the mean birth weight was 3.25 ± 0.64 kg. The median age at presentation was 9.5 days (IQR, 6.75-15.00 days). All patients presented with scrotal erythema and swelling, while fever occurred in 30.0% of cases. Right-sided involvement predominated (56.7%). Common local complications included hydrocele (66.7%), orchitis (43.3%), and scrotal abscess (20.0%). Systemic complications included hyperbilirubinemia (16.7%), neonatal pneumonia (13.3%), and sepsis (10.0%). Scrotal ultrasonography established the diagnosis in all patients. Urinalysis was performed in 19 infants, all of whom had normal results. Among 11 patients who underwent culture testing, 4 yielded positive results, including Escherichia coli (n = 2), Kluyvera ascorbata (n = 1), and Salmonella Hillingdon. (n = 1). Four infants underwent incision and drainage because of abscess formation. During follow-up (median, 13 months), no obvious testicular atrophy or recurrence was observed.

conclusionNeonatal epididymitis is a rare condition often associated with local complications such as orchitis and hydrocele, as well as systemic infections. A normal urinalysis does not exclude the diagnosis. Early ultrasonography plays a crucial role for differentiating epididymitis from testicular torsion and may help avoid unnecessary surgical exploration.
