Pie Chart from Scientific Research

At the time of collection, brains were dissected sagittally and visually assessed to determine whether a macroscopic tumor was present. Samples were classified accordingly into two categories depending on tumor status: “tumor” (when a tumor was present) or “no macroscopic tumor” (when no clear tumor mass was observed). Pie charts show the distribution of these categories within each treatment group at days 14 and 21.
