abstract="<b>Objective</b>: To determine chronic traumatic encephalopathy (CTE)-related publication characteristics associated with higher Altmetric scores.<b>Methods</b>: A systematic review of the CTE literature was conducted using PubMed. Publications were coded for: journal impact factor (JIF); publication type (primary versus non-primary data collection); discussion of American football; contact sport-CTE association conclusion (yes versus no/neutral); and Altmetric score. Multivariable ordinal logistic regression identified predictors of higher Altmetric scores.<b>Results</b>: Most of the 270 CTE-related publications did not include primary data collection (60%). The median Altmetric score was 12 (range = 0-3745). Higher Altmetric scores were associated with primary data collection [Odds ratio (OR)<sub>Adjusted</sub> = 2.29; 95% confidence interval (CI) = 1.35-3.89] and discussing American football (OR<sub>Adjusted</sub> = 2.11; 95%CI = 1.24-3.59). Among publications concluding contact sport-CTE associations, higher Altmetric scores were associated with higher JIF (3-point-JIF-increase OR<sub>Adjusted</sub> = 2.11; 95%CI = 1.24-3.59); however, the association of higher Altmetric scores with higher JIF was not found among neutral publications or those concluding no contact sport-CTE associations (3-point-JIF-increase OR<sub>Adjusted</sub> = 1.07; 95%CI = 0.94-1.22).<b>Conclusions</b>: Most CTE-related publications (60%) did not involve primary data collection. Publication characteristics such as higher JIF and concluding contact sport-CTE associations were associated with higher Altmetric scores. It is important for the academic community to consider strategies to counter publication and promotion bias in the presentation of CTE literature.<p /> <p>Language: en</p>",
