Yearning to incorporate osteoarthritis-based age estimates into your casework!? Look no further! :D
The new OA-TA GUI was peer reviewed as part of an abstract accepted for presentation at the 2024 American Academy of Forensic Sciences meeting. You can download v1 here!
OA-TA utilizes presence/absence scores for OA in up to nine synovial joints to generate age-estimate intervals, or floor/ceiling age estimates, for modern U.S. adults. Based on analyses of OA in 408 skeletal donors from the UTK Donated Skeletal Collection, previous publications by Winburn and Stock (2019) and Strasheim et al. (2023) used transition analysis—binomial generalized linear models (GLMs) with the probit link function—to generate age estimates based on the age at which 90% or 95% of the population transitions from ‘no OA present’ to ‘OA present’ in the joints for which scores were entered. The OA-TA GUI represents the practical implementation of this work, and we are excited to share it with you!
