(A, B) Working memory in oral contraceptive users versus non-users. Boxplot showing partial residuals of working memory test to remove the effect of age and education based on a generalized least square model. Working memory was tested with the Letter-Number-Sequencing (LNS) (A) test and the Symbol-Digit-Modalities-test (SDMT) (B) in oral contraceptive-users (OC-users) and women using no oral contraceptives (non-users). There was no difference between OC-users and non-users on the LNS (p = 0.9), but a trend towards better performance in OC-users was observed on the SDMT (p = 0.14). WM, working memory; LNS, Letter-number-sequence test; SDMT, Symbol-Digit-Modalities test; OC, oral contraceptive; CAR, cortisol awakening response.
