Forestplot of meta-analysis model of optimum anticoccidial activity (POAA) with different treatments in ASTs 1 and 4 (challenge with E. maxima). T03: lasalocid, T04: maduramycin T05: decoquinate, T06: nicarbazin+semduramicin, T07: monensin, T08: salinomycin, T09: narasin+nicarbazin, T 10: nicarbazin. Blue square are the mean of POAA in each experimental group and each AST; red diamond represents pooled effect of all experimental groups considered.
