Self-Selected or Mandated, Open Access Increases Citation Impact for Higher Quality Research

Figure 11

Exp(ß)-1 values for logistic regressions (JIF 2.47–29.96).

(See Figure 5 for explanation of analysis and interpretation.) In this, the highest JIF range, article age again increases citations in all ranges, whereas OA again has its effect only in the top range (lo/hi) (Note the anomalous effect of the “Review” variable; this is probably because it is confounded with the Reference count variable; when Review was removed in further analyses, the pattern of the other variables, and in particular OA, was unchanged.)
