For the sake of brevity, only the results from the marginal age-residence and age-residence-year analyses are reported here because there was little variation among the other results (which are available on request).
Mixing quality has been quantified with spatial data statistics, maximum striation thickness and residence time analyses.
To examine the effect of multiple residences, our analyses were restricted to residences of longest duration.
For residence-specific analyses, we excluded cases of invasive GAS infection if residence was missing or unknown.
The impact of the intervention on work routines in community residences is analysed by ordinal regression analysis.
To examine the effect of multiple residences, we restricted our analyses to residences of longest duration.
True residence time distribution analyses for the overall column as well as individual regions, i.e., the riser, the downcomer, the top, and the bottom regions, are conducted for the first time based on CARPT measured particle trajectories.
In the analyses, "residence" was significantly associated with the decision to participate.
Despite adjusting for region of residence in the analyses, the possible impact of this on the results, is difficult to assess.
MIE workers and nearby residents were grouped according to tertiles for duration of employment and years spent at residence before statistical analyses.
While this explanation may hold for associations based on bivariate relationships, the positive association has been observed to persist even after controlling for urban/rural residence in multivariate analyses [ 19], implying that there exists other important explanations.
