The line graph illustrates the average weekly number of patients visiting four different clinics at a hospital between 2010 and 2016.
Overall, the eye clinic experienced by far the most substantial growth and became the busiest clinic by 2016. In contrast, the birth-control clinic fluctuated considerably, although its figure returned to its initial level at the end of the period. The diabetic and dental clinics both recorded overall increases, despite some fluctuations.
In 2010, the birth-control clinic had the highest number of weekly patients, at approximately 240, while the corresponding figure for the eye clinic was 120. Attendance at the birth-control clinic subsequently increased to 280 in 2012, before falling sharply to 180 in 2014. It then recovered to around 240 in 2016. Meanwhile, the eye clinic followed a consistent upward trend, with its weekly patient numbers rising from 120 in 2010 to 150 in 2012, then increasing substantially to 250 in 2014 and reaching approximately 350 by 2016.
The diabetic and dental clinics recorded considerably lower figures for most of the period. Attendance at the diabetic clinic increased from roughly 70 patients per week in 2010 to 90 in 2012 and remained at this level in 2014. It then doubled to approximately 180 in 2016. The dental clinic, by contrast, initially declined from around 100 patients in 2010 to just 60 in 2012. However, its figure subsequently recovered to approximately 120 in 2014 and rose slightly further to 130 by 2016.
