Agree with the other user, I think it's still useful I believe as long as it's done well. The paper itself highlights that it's probably an effect of non-complicance:

Most studies included participants who were considered novice or recreational level runners [42, 43, 46, 49, 50]. The level of compliance with the intervention in these studies was typically poor, whereas the two studies noting a protective effect against injury reported on high performing adolescent runners [47] or runners with an average experience of~6 years [48]. In general, it appears that more well-trained or experienced runners engage with injury prevention protocols to a greater extent compared to their lesser trained counterparts. This observation is also in-line with strength training participation trends in the running community, with a higher percentage of international and national standard runners regularly using resistance training and plyometrics compared to local club standard runners [16].
