“…The behavioural change is a phenomenon that has been documented in the clientele of SIFs in Canada and Europe, where such PWID are less likely to share their needles once they leave the injection facility (Bravo et al [7, 37, 39]). This rate has been incorporated in Bayoumi and Zaric [5], Bayoumi et al [6], Andresen and Boyd [3], Andresen and Jozaghi [4], Jozaghi [27, 28]), Jozaghi and Jackson [30], Jozaghi et al [31]), Jozaghi et al [32]), and Jozaghi et al [33] because of the empirical evidence shown in Kerr et al [37, 39]) and Bravo et al [7]. Ultimately, similar to Bayoumi and Zaric [5], Bayoumi et al [6], Jozaghi [29], Jozaghi et al [32]) and Jozaghi et al [33], this study considered 50 % of the reported effects of a SIF on needle sharing.…”
