We acknowledge that the data (bar charts, line graphs, markers and error bars on the graphs, distance between the ticks on the axes) in this article are presented as such due to the limitations of the software at the time, but this does not impact the conclusions of the study. Due to the age of the paper, it is not possible to render the figures again to match the current guidelines and norms.
