Fig.4a, bFrom: How do porosity-inducing techniques affect antibiotic elution from bone cement? An in vitro comparison between hydrogen peroxide and a mechanical mixerCorrelation between porosity and total elution amount. Total elution amount was calculated by adding all the elution data obtained in one week per sample. Shown are individual values for all 5 samples in each ALBC preparation. a Moderate correlation was observed between the total porosity and total elution (p = 0.0237, r = 0.448). b No correlation was observed between surface porosity and total elution amount (p = 0.7813, r = -0.059)Back to article page
