Lab 6 -0.053* 12
Lab 7 0.044* 43
Lab 8 -0.145* 19
F-statistic p-value <.001  
Brain Quality difference Sample size
Lab 1 -0.054* 201
Lab 2 0.016 24
Lab 3 0.029* 31
Lab 4 0.229* 42

F-statistic p-value <.001  
  1. ANOVA model effects for GNUSE median across labs, for two tissue types - bone marrow and brain. There is a statistically significant difference in quality between labs in both tissue types (F-test p-values < 0.001). A * denotes a statistically significant lab effect.
