In biliary atresia, cholangiography still remains the diagnostic gold standard.

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
Early diagnosis of biliary atresia (BA) is essential to maximize the success of Kasai portoenterostomy. We read with interest the recent study reporting excellent diagnostic performance of abdominal ultrasonography combined with serum gamma-glutamyl transferase (GGT) for the diagnosis of BA. While these findings are encouraging, their applicability to younger infants deserves caution, as the study cohort was diagnosed relatively late. During the earliest stages of BA, ultrasonographic findings, serum GGT levels, and even liver biopsy may be less reliable, increasing the risk of delayed diagnosis. When BA remains clinically suspected, preserving the therapeutic window for Kasai portoenterostomy should take precedence, and cholangiography should remain the diagnostic gold standard rather than be delayed by repeated non-invasive investigations.
