Fig. 2. — Presentation and interpretation of primary outcome “time to obtain an optimal granulation tissue,” using CI in relation to non-inferiority margin. Dashed lines indicate non-inferiority margin; the region between dashed lines is zone of non-inferiority. Error bar indicates 2-sided 95% CI. Given that CI for the difference in mean times (ALGINATE minus NPWT) lies to the left of the non-inferiority margin [Δ, (+ 4 days)] and also include 0, the interpretation is ALGINATE is non-inferior to the NPWT but not shown to be superior.
