Fig. 3. Temporal expansion of 29 large MSM clusters (7+ primary infections) over the last decade.

Fig. 3

Box and whiskers plots represent the episodic transmission intervals of each cluster, with Tukey whiskers showing 1.5 time interquartile intervals and severe outliers (●). Four transmission clusters showed biphasic expansion with initial (light grey) and secondary outbreaks (dark grey). Clusters harbouring resistance to nonnucleoside reverse transcriptase inhibitors have been dashed. The sizes of each transmission cluster are denoted in parenthesis. Clusters 68, 50 and 99 harbouring transmitted resistance to NNRTIs are dashed.
