Clinical relevance of impaired consciousness in accidental hypothermia: a Japanese multicenter retrospective study.

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
aimThis study aimed to investigate the association between level of impaired consciousness and severe hypothermia (<28°C) and to evaluate the association between level of impaired consciousness and inhospital mortality among accidental hypothermia patients.
methodsThis was a multicenter retrospective study using the J-Point registry database, which includes data regarding patients whose core body temperature was 35.0°C or less and who were treated as accidental hypothermia in emergency departments between April 1, 2011 and March 31, 2016. We estimated adjusted odds ratios of the level of impaired consciousness for severe hypothermia less than 28°C and inhospital mortality using a logistic regression model.
resultsThe study included 505 of 572 patients in the J-Point registry. Relative to mildly impaired consciousness (Glasgow Coma Scale [GCS] 13-15), the adjusted odds ratios for severe hypothermia less than 28°C were: moderate (GCS 9-12), 3.26 (95% confidence interval [CI], 1.69-6.25); and severe (GCS < 9), 4.68 (95% CI, 2.40-9.14). Relative to mildly impaired consciousness (GCS 13-15), the adjusted odds ratios for inhospital mortality were: moderate (GCS9-12), 1.65 (95% CI, 0.95-2.88); and severe (GCS < 9), 2.10 (95% CI, 1.17-3.78).
conclusionThe level of impaired consciousness in patients with accidental hypothermia was associated with severe hypothermia and inhospital mortality.
