Late-onset vitamin K deficiency presenting as haemorrhagic shock and severe multi-system organ failure.
Article in BMJ case reports, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Vitamin K is an essential dietary cofactor required for the synthesis of active forms of vitamin K-dependent procoagulant proteins. Vitamin K deficiency, particularly late-onset deficiency occurring between 1 week and 6 months of age, can cause a life-threatening bleeding disorder. An exclusively breastfed, full-term, 6-week-old infant male presented with severe haemorrhagic shock and multi-system organ failure related to caregiver refusal of intramuscular vitamin K after birth. Coagulation studies were normalised within 8 hours of intramuscular vitamin K administration. An increasing number of caregivers are refusing intramuscular vitamin K which has led to a rise in the incidence of vitamin K deficiency bleeding. Health policy organisations around the world emphasise the benefits of intramuscular vitamin K and risks of refusal, particularly in exclusively breastfed infants who are at higher risk due to low vitamin K levels in breast milk. This case highlights the multi-system severity of this life-threatening yet preventable disorder.
