Hypothermic cardiac arrest: prognostic factors for successful resuscitation before rewarming.
Article in Scandinavian journal of trauma, resuscitation and emergency medicine, 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
objectiveTo indicate factors predicting return of spontaneous circulation in patients with hypothermic cardiac arrest in the pre-rewarming period.
methodsA multicenter retrospective study was conducted. We included patients who had suffered cardiac arrest caused by severe accidental hypothermia with a core body temperature of ≤ 28 °C. Patients who had achieved return of spontaneous circulation before commencement of active rewarming at the hospital were compared to those who remained in cardiac arrest.
resultsA total of 156 patients suffering hypothermic cardiac arrest were included in the study. In 14 of them (9%) resuscitation was successful before rewarming. Factors associated with return of spontaneous circulation were as follows: witnessed onset of cardiac arrest (p = 0.04); a higher core body temperature (p = 0.005) with a prognostic threshold of 24.6 °C; and a higher arterial oxygen partial pressure (p = 0.04) with a prognostic threshold of 81 mmHg. One patient after successful resuscitation sustained recurrence of cardiac arrest during rewarming.
conclusionsPatients with core body temperature < 25 °C, hypoxemia, and those who sustained unwitnessed hypothermic cardiac arrest have weak chances for successful resuscitation before rewarming. They can benefit from immediate transportation to an extracorporeal life support facility under continuous cardiopulmonary resuscitation. Effective rewarming and oxygenation during the prehospital period can increase the chances for return of spontaneous circulation. Recurrence of cardiac arrest during rewarming is uncommon.
