Extended Data Fig. 4: Odds ratios of resistance to each of the antibiotics for past purchases of different drugs across a range of purchase-to-sample time intervals: adjustments for demographics and cross-resistance.

a, Multivariate logistic regression models for the association of each antibiotic resistance with past purchases of the indicated drugs not accounting for cross-resistance (Methods: Logistic regression ‘Purchase history’. Same graphical scheme as in Fig. 4a,b). b, Logistic regression model as in a adjusted for cross-resistance (Methods: Logistic regression ‘Purchase history adjusted for cross-resistance’). c, Logistic regression model as in a adjusted for demographics (Methods: Logistic regression ‘Purchase history adjusted for demographics’. Gray asterisks indicate statistical significance and non-significant values, with Bonferroni corrected P > 0.05, are blanked.
