Exploring the clinical translation intensity of papers published by the world's top scientists in basic medicine

The extent to which basic medical research is translated into clinical practice is a topic of interest to all stakeholders. In this study, we assessed the clinical translation intensity of papers published by scientists who have made outstanding contributions to the field of basic medicine (Lasker Prize winners for Basic Medical Research). Approximate Potential for Translation (APT), Translational science scores (TS), and Citations by clinical research (Cited by Clin.) were analyzed as dependent variables. A traditional citation indicator was used as a reference (relative citation ratio, RCR). In order to examine the correlation between these different indicators and the characteristics of the paper, the author, and the institution. we used nonparametric tests, Spearman correlations, ordinal least squares regressions (OLS), quantile regressions, and zero-inflated negative binomial regression methods. We found that among the basic medical research papers published by Lasker Basic Medicine Award winners, (1) 20% are cited by clinical research; 11.6% of the papers were more valuable for clinical research than basic research; 12.8% have a probability of more than 50% to be cited in future clinical studies; (2) Spearman correlations were conducted among APT, TS, Cited by Clin., RCR, and all of the other continuous variables. There is a significant, positive, low to moderate correlation between APT, TS, and Cited by Clin (APT and TS: r = 0.549, p < 0.01; APT and Cited by Clin: r = 0.530, p < 0.01; TS and Cited by Clin: r = 0.383, p < 0.01). However, the relationship between RCR and the three indicators of clinical translation intensity was not consistent. APT was positively correlated with RCR (r = 0.553, p < 0.01). Cited by Clin. is weakly positively correlated with RCR (r = 0.381, p < 0.01). There is almost no correlation between TS and RCR (r = 0.184, p < 0.01). (3) Publication age, primary research paper, multidisciplinary science, number of disciplines, authors, institutions, funded projects, references, length of the title, length of paper, physical age, gender, nationality, institutional type, Nobel Prize have a significant relationship with 1 to 3 types of clinical translation intensity measures. In a sample of basic medical research papers published by the world's top scientists in basic medicine, we came to the following conclusions: the three indicators, APT, TS and Cited by Clin., measured the clinical translation intensity of the papers from different perspectives. They are both related to each other and have their own characteristics. In a sample of basic medical research papers published by the world's top scientists in basic medicine, characteristics at the paper, winner, and institution level significantly correlated with the measures of clinical translation intensity. Gender effect on the clinical translation intensity of papers was confirmed. Traditional citation-based indicators and translational-focused indicators measure academic impact and clinical impact respectively. There is a certain degree of disconnect between them. Two types of indicators should be used in combination in future assessments of basic medical research.
