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

backgroundPercutaneous liver biopsy (PLB) is an important procedure in the diagnosis and follow-up of paediatric liver disease. Its purpose is to obtain tissue for histopathological observation, in our case, with ultrasound (US) guidance.

objectiveTo evaluate the effectiveness and safety of US-guided PLB in children. MATERIAL AND

methodsA retrospective study over a period of 12 years, from January 1999 until December 2010, with a selection of US-guided PLB performed in children with focal liver lesions or diffuse hepatic disease and liver transplant (LT). A 16-gauge automatic needle was used and a maximum of three fragments of liver were collected. Contraindications were: bile duct dilatation (>3 mm) INR > 1.5 (reference range, 0.9 -- 1.2) and platelet count <50,000 (reference range, 150,000 -- 450,000). Analysis focused on complications and final diagnosis.

resultsA total of 513 biopsies were performed, 379 (73.9%) in children who had undergone orthotopic LT, 117 (22.8%) in children with liver disease of unknown cause and 17 (3.3%) in children with focal hepatic lesions. Histological diagnosis was obtained in 509 of 513 (99.3%) biopsies performed. Minor complications were registered in 38 patients (7.4%) and major complications occurred in 5 patients (1%). None needed a surgical intervention.

conclusionUS-guided PLB in children is a safe and efficient method to achieve a specific diagnosis in liver disease.
