Acute aortic thrombosis following umbilical artery catheterisation in extremely low birthweight infants: walking the tight rope of management.
Article in BMJ case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Umbilical artery catheterisation (UAC) is crucial in the management of clinically sick infants. One of its dreaded complications is aortic thrombus formation which accounts for significant morbidity and mortality. We present the case of a premature infant born at 32 weeks of gestation and with a birth weight of 960 gm, who developed signs of acute lower limb ischaemia following UAC cannulation. Ultrasound Doppler scan confirmed large aortic thrombus involving iliac arteries. Heparin infusion was started with clinical improvement over the next 12 hours and eventual complete resolution of clot size. This case underscores the importance of prompt detection of acute aortic thrombosis and cautions the use of heparin infusion in preterm infants can be lifesaving. Management can be challenging as risk of bleeding from anticoagulation and thrombolytic therapy can be catastrophic in extreme low birthweight premature infants and need to weigh with risk of severe intravascular haemorrhage.
