USP recently discovered an error with the Characterization of Apex Vessel Geometries and Irregularities Stimuli article in Pharmacopeial Forum 51(1) [Jan–Feb. 2025]. An incorrect version of Figure 6c (Skewness plot for axis-cylinder and -hemisphere perpendicularity) appeared in the article.
The correct Figure 6c appears below.
USP apologizes for any inconvenience this may have caused. The Stimuli Article will be revised and republished in a future PF.
Should you have any questions, please contact Margareth Marques, Senior Principal Scientific Liaison, Science-General Chapters (301-816-8106 or mrm@usp.org).
