Correction to Figure: The parts of figure 1 are in the wrong place so that the results and the figure legend refer to the wrong bar chart; the chart shown as 1c (workplaces) should be at the top of the figure as 1a, thereby shifting 1a (homes) to 1b, and 1b (extending law) to 1c. In the legend for 1b, ‘by socio-economic status’ is incorrect and should be omitted.
