Postnatal outcomes of referred cases with abnormal ultrasound findings of fetal gall bladder and cyst in the fetal liver.

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
objectiveTo evaluate the postnatal outcomes of referred cases with abnormal findings in the fetal gallbladder (GB) or cysts in the fetal liver.
methodsThis retrospective study included pregnant women referred to a tertiary referral unit, the fetal therapy center at Ulsan Asan Medical Center in Korea, between June 2005 and October 2022. Persistent non-visualization of the fetal gallbladder (NVFGB) was defined as non-visualization at least twice using an ultrasound scan. Antenatal ultrasound findings were obtained from the medical records, and the clinical, radiological, and surgical findings of the babies were reviewed.
resultsA total of 113 referred patients were evaluated. Most enlarged and small GBs were identified as normal or GB stones, sludge, septate GB, or choledochal cysts (CDC). NVFGB was identified postnatally in 77.5% of cases. Persistent NVFGB was identified postnatally as biliary atresia (3/14; 21.4%), hepatic parenchymal disease with cholestasis (2/14; 14.2%), or isolated GB agenesis (6/14; 42.8%). The majority of cysts in the fetal liver cases with visualization of the fetal GB were identified as CDC. Half of the patients (2/4) with CDC who underwent NVFGB were confirmed to have biliary atresia.
conclusionExcept for persistent NVFGB, most abnormal ultrasound findings in fetal GB were associated with good postnatal outcomes. Cysts in the fetal liver with visualization of the fetal GB did not result in serious adverse outcomes. NVFGB, especially persistent NVFGB with or without cysts in the fetal liver, should be followed up closely prenatally and postnatally.
