Patent processus vaginalis: role of ultrasound in pediatric population with unilateral inguinal hernia and other predictors.
Article in Pediatric surgery international, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
introductionInguinal hernia (IH) repair is a common procedure in the daily practice of pediatric surgeons. In a developing country with limited facilities, it is important to be able to predict and diagnose contralateral patent processus vaginalis (CPPV) to avoid the risk and cost of further surgery.
objectivesTo assess the accuracy of ultrasound for the detection of CPPV, using laparoscopic evaluation as a confirmatory test. We also looked for various predictors of CPPV in our study population.
methods141 patients were included in this 2-year, cross-sectional prospective study. Inclusion criteria were unilateral inguinal hernia elective patients with no major comorbidities and aged between 2 months and 8 years. Each patient was assessed in outpatient clinics and then a pre-operative ultrasound was conducted. This was followed by laparoscopic evaluation during repair of the hernia.
resultsOf the 141 patients included, 110 (78%) were males, 121 (85.9%) were born at full term, and 96 (68.1) had right-sided hernia. Mean age was 2.64 ± 1.9 years. Ultrasound was 85.7% sensitive in the detection of CPPV, 90.8% specific, and 90.1% accurate. In our analysis of patients younger than 1 year, right-sided hernia and defect size more than 10 mm were statistically significant predictors for a CPPV.
conclusionsUltrasound has a high accuracy profile and is a useful alternative in limited resource settings with restricted access to minimally invasive surgery for the prediction of CPPV. Patients younger than 1 year with a right-sided hernia or a manifested hernia defect larger than 10 mm are at a higher risk of having a CPPV.
