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

Fetal MRI is increasingly used to confirm prenatal ultrasound findings or to provide additional relevant information in cases of abnormal ultrasound results. Most commonly, MRI is performed to evaluate suspected central nervous system lesions. However, other fetal anomalies may also warrant further assessment with MRI. We present MRI findings in a case of unilateral fetal renal vein thrombosis (RVT) in a monochorionic diamniotic (MCDA) twin pregnancy complicated by twin-twin transfusion syndrome (TTTS). Following laser photocoagulation, a unilateral renal abnormality was detected in one of the twins during follow-up ultrasound, prompting fetal MRI. MRI findings led to the diagnosis of unilateral RVT, which was subsequently confirmed on postnatal ultrasound.
