Relationship between overall 6-monthly needle and syringe provision (NSP) and HIV incidence among PWID across all three drop-in centres, 2012–2020. (a) NSP coverage is plotted on the left axis (in black) alongside HIV incidence on the right axis (pink) for each 6-month period over 2012–2020. (b) Correlation of NSP coverage and HIV incidence among PWID, using the 6-monthly data points from 2012 to 2020. The shaded area indicates the 95% confidence intervals for the best linear regression model line, with the R2 and p-values indicated.
