Cohen's kappa (κ) was calculated for CFHO, CCO, Scler CrAE, DJD, and suspected CHD, and weighted κ was calculated for DJD score to determine inter‐ and intraobserver agreement.</p> </sec> <sec id="vsu12309-sec-0005" sec-type="section"> <title>Results</title> <p>Intraobserver agreement on CFHO, CCO, Scler CrAE, DJD, and suspected CHD ranged from slight to almost perfect, but was not significantly different between NBC, DECVS, and DECVDI. Radiologists and non‐board certified observers had a more uniform scoring than surgeons on the overall DJD score, as did academics versus non‐academics.</p> <p>Interobserver agreement for NBC was more uniform than that of radiologists and surgeons on CCO and DJD. NBC and radiologists scored more uniformly than surgeons on CFHO, and radiologists scored more uniformly than NBC and surgeons on Scler CrAE. Academics scored more uniformly than non‐academics, but only significantly for Scler CrAE.</p> </sec> <sec id="vsu12309-sec-0006" sec-type="section"> <title>Conclusions</title> <p>Recognition of specific radiographic markers is only fairly reliable within and between experienced observers. Therefore, care must be taken to apply these traits in official screening, surgical decision‐making and scientific research.</p> </sec> </abstract>
