Submissions were separated into two main categories, ranked and non-ranked, and statistical analysis was performed for each category. We note that the non-ranked category included all submissions, methods denoted as ranked or non-ranked. The ranked category analysis, which was for the formal competition, only considered methods denoted as ranked. All data, analysis plots and tables for ranked and non-ranked categories were made available in the relevant SAMPL9 GitHub repository as "Ranked Accuracy" or "All Accuracy"( SAMPL9/tree/main/host_guest/Analysis).
