Patient Perceptions of Natural Orifice Translumenal Surgery

Table 3

Associations between patient characteristics and opinions. Please see the appendix for detailed responses. Scales are scored from 1–5, with 1 representing no importance, bother, interest, or no increased acceptable risk; 5 = extremely important, bothered, interested, and a 20% increased risk. Values represent means and standard deviations, but 𝑃 values are based on the Mann-Whitney U or the Kruskal-Wallis as appropriate.
