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

purposeTo analyze the value of ultrasonography in predicting metachronous contralateral inguinal hernia (MCIH) and diagnosing contralateral persistent processus vaginalis (CPPV) in children with unilateral inguinal hernia, a prospective study was conducted.

methodsAll participants underwent a preoperative ultrasound on the contralateral groin. Patients in group A1 received operating procedure according to ultrasound results (patients with negative contralateral US results received hernia repair on the affected side), and patients in group A2 received operation according to laparoscopic results (patients received hernia repair and CPPV ligation). All patients were followed up 2 years and compared to a historical control (group B) who underwent open hernia repair only on the affected side regardless of contralateral US results.

resultsIn groups A1 and A2, laparoscopic exploration revealed the presence of a CPPV in 490 cases. Ultrasound was found to be accurate in 104 out of the 490 cases with four false-positive and 386 false-negative results. This yielded an accuracy of 59.3%, a sensitivity of 21.2%, and a specificity of 99.2%. 10 patients in group A1, and 74 patients in group B developed MCIH. The accuracy, sensitivity, and specificity of the value of ultrasonography in predicting MCIH were 89.3%, 52.4%, and 92.5%, respectively.

conclusionsPreoperative ultrasonography of the contralateral groin is currently unable to accurately detect CPPV, but it appears to be a promising method in predicting MCIH by using rigorous diagnosing criteria.
