The conclusion states "The considerable number of included papers reporting a statistically insignificant result decreases the usual concern over publication bias". I disagree with this. Firstly, the number of p-values labeled "non significant" in Table 3 was 15 out of 48 (31%), which I would not call "considerable". More importantly, if nudges are not effective then there should be many negative studies, so there still could be a large publication bias. Searching for registered studies that used a nudge but were never published would give some evidence of potential publication bias.
