Comparison of erythrocyte invasion inhibition phenotypes of Plasmodium falciparum isolates across 3 years in The Gambia. A Neuraminidase, B low trypsin, C chymotrypsin, and D chymotrypsin and low trypsin. Each box shows the invasion efficiencies in enzyme-treated erythrocytes relative to untreated erythrocytes, and the horizontal black lines in each box represent the median. P values < 0.05 were considered statistically significant
