Yeah, this highlights yet again the importance of meta-analyses (i.e. a study that takes all the available data from all the studies published on the topic in the past to reanalyze this data and obtain better statistical significance from it).
The author actually mentions this.
(emphasis mine)
Similarly, in particle physics people are very careful about anomalies in the data that might hint at a new particle. Only if the statistical significance is large enough (how many sigmas) will they report on it.
