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
BACKGROUND Insulin deficiency can cause hypothermia by preventing glucose uptake into cells, and acidosis can impair metabolic rate. Diabetic ketoacidosis (DKA) and a body temperature <35°C (hypothermia) is a combination with a high mortality rate due to refractory cardiocirculatory collapse and requires emergency management. Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is a rescue therapy to restore perfusion, rewarming, and manage cardiac arrest. This report describes the case of a 48-year-old man with DKA, hypothermia, and cardiac arrest managed with VA-ECMO. CASE REPORT A 48-year-old man with impaired glucose tolerance presented with unconsciousness and severe hypothermia (body surface temperature: <30°C), DKA (glucose concentration: 58.8 mmol/L, pH: 6.853, HbA1c: 11.1%), and subsequent ventricular fibrillation requiring cardiopulmonary resuscitation. Despite return of spontaneous circulation and conventional therapy, including insulin, fluid resuscitation, and vasopressor support, refractory cardiogenic shock unresponsive to maximal medical therapy required VA-ECMO. His temperature was maintained at 32°C for 24 h for neuroprotection, followed by controlled rewarming. Intensive metabolic management with continuous insulin therapy achieved rapid correction of hyperglycemia (52.2 to 12.1 mmol/L) and hyperosmolality (392 to 327 mmol/kg) within 72 h. Acidosis resolved rapidly, with progressive recovery of renal function, which allowed weaning from VA-ECMO on day 4 and extubation on day 8. Despite concerns for cerebral injury, brain magnetic resonance imaging (MRI) showed no major hypoxic-ischemic damage. The patient achieved good functional recovery. CONCLUSIONS VA-ECMO provides essential dual functionality as circulatory support and precise temperature control in complex metabolic emergencies, enabling successful management of diabetic ketoacidosis-associated hypothermia and cardiac arrest.
