Figure 8. Change in percentage of validated articles reporting different types of validation before (2003) and after (2017) the journals with guidelines implemented antibody reporting guidelines.

Sample size (identical for all types of validation): with guidelines 2003 n = 20, 2017 n = 23; without guidelines 2003 n = 15, 2017 n = 15. P-values were determined with Fisher’s exact test and adjusted using the Holm-Bonferroni correction. All adjusted p-values are 1.
