: To determine chronic traumatic encephalopathy (CTE)-related publication characteristics associated with higher Altmetric scores.: 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.: 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) = 2.29; 95% confidence interval (CI) = 1.35-3.89] and discussing American football (OR = 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 = 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 = 1.07; 95%CI = 0.94-1.22).: 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.
确定与较高的Altmetric评分相关的慢性创伤性脑病（CTE）相关出版物特征。
使用PubMed对CTE文献进行系统综述。对出版物进行编码的内容包括：期刊影响因子（JIF）；出版物类型（原始数据收集与非原始数据收集）；对美式橄榄球的讨论；接触性运动与CTE关联结论（是与否/中立）；以及Altmetric评分。多变量有序逻辑回归确定了较高Altmetric评分的预测因素。
270篇与CTE相关的出版物中，大多数（60%）不包括原始数据收集。Altmetric评分中位数为12（范围=0-3745）。较高的Altmetric评分与原始数据收集相关[比值比（OR）=2.29；95%置信区间（CI）=1.35-3.89]以及对美式橄榄球的讨论相关（OR=2.11；95%CI=1.24-3.59）。在得出接触性运动与CTE关联结论的出版物中，较高的Altmetric评分与较高的JIF相关（JIF增加3分，OR=2.11；95%CI=1.24-3.59）；然而，在中立出版物或得出无接触性运动与CTE关联结论的出版物中，未发现较高的Altmetric评分与较高的JIF相关（JIF增加3分，OR=1.07；95%CI=0.94-1.22）。
大多数与CTE相关的出版物（60%）未涉及原始数据收集。较高的JIF以及得出接触性运动与CTE关联结论等出版物特征与较高的Altmetric评分相关。学术界在呈现CTE文献时考虑应对出版和推广偏差的策略很重要。
