As vital as we are, there is an increased incidence of family breakdown in these households.
To estimate whether a new surgical technique is associated with lower incidence of postoperative breakdown of the vaginal cuff after laparoscopic hysterectomy or trachelectomy, compared with previous methods of closure.
In contrast, the wider literature tends to focus on problematic relationship issues and the high incidence of family breakdown with fathers leaving and losing contact with their children [ 8, 9, 11].
Across the entire post-trial period, the incidence of confirmed breakdowns inside proactive culling areas was 37.6% lower (95% CI: 24.6% to 48.4% lower) than that inside no-culling areas (Table 1).
Across the combined during- and post-trial period, the incidence of confirmed breakdowns was 28.7% lower (95% CI: 20.8% to 35.8% lower) in proactive areas than in no-culling areas.
As in previously published analyses [10], [11], we extrapolated from our results to estimate the size of an idealised circular culling area that would need to be targeted to obtain an overall reduction in the incidence of confirmed breakdowns, with detrimental effects outside the targeted area offset by beneficial effects inside.
For the 30-month period when effects were detectable inside trial areas, the incidence of confirmed breakdowns on lands ≤2 km outside proactive culling areas was comparable (6.0% lower, 95% CI: 29.7% lower to 25.7% higher, p = 0.68) with that ≤2 km outside no-culling areas.
Across the entire combined during- and post-trial period, the incidence of confirmed breakdowns on lands ≤2 km outside proactively culled areas was comparable (11.7% higher, 95% CI: 12.9% lower to 43.2% higher, p = 0.38) with that ≤2 km outside no-culling areas.
Across the entire post-trial period, the incidence of confirmed breakdowns on lands ≤2 km outside proactive culling areas was comparable (5.6% lower, 95% CI: 31.4% lower to 30.0% higher, p = 0.73) with that ≤2 km outside no-culling areas (Table 3).
…the incidence of herd breakdowns in reactively culled areas has been consistently greater than expected.
Once the ISG's fieldwork finally resumed and the preliminary data was analysed the following year, an unexpected finding emerged, which the ISG advised ministers of immediately: …the incidence of herd breakdowns in reactively culled areas has been consistently greater than expected.
