I think a mix of 1:1 tutoring and student collaboration is the best deal. No data, but when I worked in a primary school with high % of school meal children, the literacy rate was noticeably higher when there were more literacy specialists doing 1:1 tutoring. The sessions are often 5-10 minutes but occur daily. They also have classroom literacy where they get a chance to do lots of partner work.
