Figure 3. Association between viral loads and age in inpatients and outpatients with RSV infection.

Figure 3.

Viral loads for RSV inpatients (left panel; tile dots) and outpatients (right panel; orange dots) according to age are represented using locally estimated scatterplot smoothing (LOESS) curves (in blue), which summarize the association into a single line without imposing constraints such as linearity. Based on polynomial and restricted cubic spline regression there were no significant non-linearity associations, and so linear regression lines (in black) were also fitted to the data. Mean RSV loads (log10 copies/mL) are lower by 0.02 per month for the inpatient cohort, and are higher by 0.02 per month among the outpatient group.
