However, cluster sizes in the networks from the 5–7 RTI group showed a trend towards less increase over time compared to clusters from networks from the 0–2 RTI group (negative binomial GLM: 5–7 RTI group estimate = − 0.3, p = 0.071), which coincided with a higher number of clusters retained in the 5–7 RTI networks.
