Relationship between initial growth rates and fitness. Association between initial relative growth rate of clone R (in competition) compared to growth rate of clone S (days 3–6 post-infection) with four clone R fitness parameters: A) Total asexual parasite density, B) asexual parasite persistence, C) infectious period and D) transmission probability. Each symbol represents a single mouse, orange diamonds are untreated infections, green asterisks are drug treated (days 6–9 post-infection) infections. Level of significance from linear regression of the slope and associated R-squared values are given for both untreated (top line) and drug treated (bottom line) infections
