Oxidative Stess Index (OSI) Condensed Questionnaire

Abstract

The oxidative Stress Index (OSI) has been shown to predict the onset of non-communicative disease. A condensed form of the OSI questionnaire has now been developed to enable meaningful OSI data to be obtained from answers to only eight questions, rather than the 400+ items contained in the original detailed questionnaire.

Oxidative Stress Index Predicts the Severity of COVID-19

“…The Oxidative Stress Index, based on a questionnaire that takes all OS elevated factors into account, has been shown to be indicative of OS level and a predictor of the likelihood of disease onset, as well as of disease severity [4]. Though originally proposed as a 400+ item questionnaire, the OSI has been modified to an eight-item condensed format [5] and subsequently proposed as a predictor of severity of COVID-19 [1].…”
