borderline significantp = 0.06
While there was a nominally increased relative risk in those with smoking (RR 3.40), immobility (RR 2.50), exsiccosis (RR 12.9) and diabetes (RR 1.20) and a decreased risk in those with renal insufficiency (RR 0.49), confidence intervals were too wide and only smoking became borderline significant (p = 0.06).
