Comparisons below the diagonal are omitted (blank cells). Blank cells above the diagonal indicate that no studies compared the interventions.

See Figure 13. Codes: A: alpha agonist, B: onabotulinum toxin A, C: anticholinergic, H: hormones, N: neuromodulation, T: behavioral therapy, U: periurethral bulking, V: intravesical pressure release, P: sham/no treatment/placebo.

Number of studies (and total sample size) comparing row and column intervention categories. Numbers across the diagonal (e.g., with A as both row and column header) are the total sample size for each intervention category. Blank cells above the diagonal imply that no studies directly compared the intervention categories.
