Table 2 Knowledge on antibiotics resistance

Code	Statements	Pre-intervention [Pre] (N = 234)	Post-intervention		p Value_*
		Pre-intervention [Pre] (N = 234)	Immediate [P1] (N = 234)	2 weeks [P2] (N = 234)
		Correct responses n (%)	Correct responses n (%)
KR1	Antibiotic resistance happens when the antibiotic loses its ability to treat bacterial infections	160 (68.4)	221 (94.4)	212 (90.6)	< 0.001
KR2	Taking leftover antibiotics from previous infection may cause antibiotic resistance	150 (64.1)	213 (91.0)	211 (90.2)	< 0.001
KR3	Treatment may fail if you do not finish antibiotics as instructed by doctors	187 (79.9)	227 (97.0)	227 (97.0)	< 0.001
KR4	Using antibiotics without consulting doctor or purchasing directly from the pharmacy without a prescription may cause antibiotic resistance	163 (69.7)	219 (93.6)	208 (88.9)	< 0.001

*Mc Nemar test was performed to analyse the difference between Pre vs P1, P1 vs P2 and Pre vs P2. The p values for Pre-intervention vs Post-intervention (immediate) and Pre-intervention vs Post-2-weeks-intervention were presented in the table (p < 0.001). p values for Post-intervention (immediate) vs Post-2-weeks-intervention were insignificant for all questions (p > 0.05)
