  1. The coefficients of the models on the logarithmic scale of the outcomes are converted to percentage changes, while the coefficient for the average citation per publications reads as a unit change. The quantities are provided together with a 95% confidence intervals (CI). For the model for the altmetric score, only data since 2010 is used, as this is a more recent metric. To model the RCR, only researchers from the LS were included so that we do not need to account for the research area. The p-values refer to the results of likelihood ratio tests for each variable to be present in the model. For the institution type University serves as reference category, for the fields it is Life Sciences. For the evaluation score the class AB-A serves as reference category and for year it is the period 06-09 for model 3, 5, 6 and 10-14 for model 4.
