Increased Thyroxin During Therapeutic Hypothermia Predicts Death in Comatose Patients After Cardiac Arrest.
Observational study in Neurocritical care, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundThe course and prognostic value of pituitary-thyroid axis hormones is not well studied after cardiac arrest. We aimed to study the prognostic role of the pituitary-thyroid axis response to resuscitation from cardiac arrest before, during and after therapeutic hypothermia.
methodsWe conducted a retrospective cohort study in consecutive comatose patients after out-of-hospital cardiac arrest who were sampled before, during and up to 48 h after a 24-h period of therapeutic hypothermia in the intensive care unit (ICU). Thyroid-stimulating hormone, total and free thyroxine (T4) and triiodothyronine (T3) were determined and compared between ICU outcome groups.
resultsWe included twenty-nine patients. TSH levels were comparable in non-survivors (n = 17) and survivors (n = 12). The free T4 levels were higher in non-survivors than in survivors (P = 0.001), whereas the free T3 levels were comparable. All samples' results similarly declined in both outcome groups up to 72 h after start of 24 h hypothermia. ROC curves analyses showed a maximum AUC of 0.83 (P = 0.003) for free T4 at the end of hypothermia with an optimal cut off ≥17.8 pmol/L to obtain 100 % specificity and positive predictive value for non-survival.
conclusionNon-survival after cardiac arrest, coma, and therapeutic hypothermia following successful resuscitation is associated with a transient increase in free T4, most probably due to inhibition of free T4 to T3 conversion. However, before routine clinical application, external validation of our finding to assess generalizability is warranted.
