Figure 5. Change in percentage of articles that reported validation information on all primary antibodies used in the study before (2003) and after (2017) two of the journals (JCN and Nature) implemented antibody reporting guidelines.

Sample size: with guidelines 2003 n = 30, 2017 n = 28; without guidelines 2003 n = 30, 2017 n = 30, total 2003 n = 60, 2017 n = 58, JCN 2003 n = 15, 2017 n = 14; Neuroscience 2003 n = 15, 2017 n = 15; Nature 2003 n = 15, 2017 n = 14; Science 2003 n = 15, 2017 n = 15. P-values (one-tailed) were determined with Fisher’s exact test and adjusted using the Holm-Bonferroni correction.
