From the existence of demonstrable amongst-study heterogeneity (see underneath), some take into account that the use of a fixed-result analysis is counterintuitive since their principal assumption is violated. Other people argue that it's inappropriate to conduct any meta-analysis when There's unexplained variability throughout trial benefits.
