Trend of RSC over time in the injection segment of each group. The RSC trends over time was investigated using mean ± standard deviation of each group and time-point. The RSC were presented as absolute RSC value (a) and relative RSC value (b) expressing as a percentage of the RSC recorded on day 1 of each group. Steroid-loaded PLGA showed a tendency of slow degradation during the initial period. (c) P-value obtained from generalized estimating equations employed to investigate whether the interaction between time and the formulation affects the RSC value.
