Change Details: In the originally published version of this article, an error originating from the provided dataset affected the calculation of grip strength, leading to an overestimation of grip strength for approximately 2,800 participants. This discrepancy arose due to a merging error by our data provider, HUNT databank, when transferring the registration fields for kilograms and grams from the paper-based protocol to digital format. The two-digit precision for the gram value was not considered in this process. Consequently, this resulted in deviations ranging from 1 to 9 kilograms.After re-running the analyses with the corrected data, the overall prevalence of frailty according to the Fried criteria increased from 10.6% to 11.7%, and according to HUNT4-FI, from 35.8% to 36.0%. The main findings and conclusions of the article remain unchanged.
