Table 1 Comparison between baseline median CFU and post cleaning median CFU for each cleaning agent

From: Use of 90% ethanol to decontaminate stethoscopes in resource limited settings

Cleaning agent Baseline Median CFU (IQR) Range of Variation Post cleaning Median CFU (IQR) Range of variation Percent reduction in CFU (mean) P value for Wilcoxon signed-rank test
IPA 22.5 (7–48) 0–110 0 (0–0) 0–21 93.14% <0.001
90% ethanol 17.5 (7–31) 0–106 0 (0–0) 0–5 97.60% <0.001
