Study of Non-Thyroidal Illness Syndrome and Its Recovery in Critically Ill Patients at a Tertiary Care Centre in South India

This is the authors' abstract. We don't add key points for this paper.

NTIS was common amongst critically ill patients (71.5%), which reversed in 61% at six weeks. Low T3 was the most common abnormality and independently predicted mortality. Free T3/free T4 also significantly predicted mortality. The correlation between thyroid dysfunction and the severity of primary illness makes it an additional attractive low-cost marker of mortality.
