Moderate-low? My understanding was that non-blinding; A vs A+B design; cognitive aspects to treatment; and subjective self-report outcomes of this sort; are almost definitive examples of a high-risk of bias: https://handbook-5-1.cochrane.org/chapter_8/table_8_5_d_criteria_for_judging_risk_of_bias_in_the_risk_of.htm … https://handbook-5-1.cochrane.org/chapter_8/8_11_2_assessing_risk_of_bias_in_relation_to_adequate_or.htm … https://drive.google.com/file/d/1pbkUAco17D0lVziiVeUTuvaBME7dACmD/view …
No it is certainly likely that the assessment was influenced. Whether this biases the study, however, is another question, and that's the point. They implemented a number of controls to reduce this bias, so I'd argue that it's not a high risk

But if you agree assessment was likely influenced then following RoB2 you necessarily get a high risk of bias in that domain. I'm not so impressed by their other controls to reduce bias, but subjective judgements on that are outside of this assessment tool anyway.pic.twitter.com/N71k4eBTat

Mmm that's the default, but as I said RoB assessment isn't a hard rule. Look at the sentence underneath the title of that graphicpic.twitter.com/ZhtiXjh7bq
