Antimicrobial resistance in Escherichia coli from Swedish piglets with diarrhoea and associations with potential risk factors

Table 7 Associations between antimicrobial resistance in Escherichia coli from study samples and potential risk factors

Link	OR	95% CI	Link strength (%)
Ampicillin resistance\| Tetracycline resistance	4.9	2.0–12.9	7
TMP-Sulfa ^a resistance\| Ampicillin resistance	27.2	9.5–93.4	30
TMP-Sulfa resistance\| >10% post-farrowing treatment	10	2.8–45.1	11
Streptomycin resistance\| TMP-Sulfa resistance	18.4	7.5–50.1	26
Neonatal diarrhoea\| Haemolysis	NA ^b	NA	35

Results from a multivariate analysis, Additive Bayesian Network (ABN) analysis investigating associations between all variables on which data were collected in this study. Results on odds ratios (OR), 95% confidence intervals (CI) and link strength of significant associations between variables are shown. ^a TMP-Sulfa = trimethoprim-sulphonamide, ^b Estimate not available due to complete data separation
