Myxoedema Coma With Type 2 Respiratory Failure and Hypothermia in an Oedematous Patient: A Case Report.
Article in Cureus, 2026. 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
Myxoedema coma is a rare, life-threatening endocrine emergency representing the most severe form of hypothyroidism. We present the case of a South Asian woman in her early 70s admitted with generalised oedema, chest pain, general malaise, and reduced appetite. Initially treated as decompensated heart failure, she deteriorated with hypothermia, hypotension, bradypnea, and reduced consciousness, requiring intensive care admission and intubation. Thyroid function testing revealed profound hypothyroidism (TSH 67 mU/L, T4 <2 pmol/L), confirming myxoedema coma. She received intravenous liothyronine and levothyroxine with clinical improvement. This case highlights the noteworthy phenomenon of cold hypercapnia alongside highlighting the diagnostic challenges of myxoedema coma, which may mimic or exacerbate cardiac and respiratory failure. Clinicians should maintain a high index of suspicion in at-risk patients, as delayed recognition and treatment significantly increase mortality.
