Figure 1.

Scatter plots with lowess smoothing comparing FEV₁ (A) and FVC (B) Z-scores of First Nations subjects whose pneumonia occurred age ≤5 years versus other subjects. Locally weighted smoothing of participants shows the reduction in lung function occurring post early childhood pneumonia. Gray hollow circles mark participants with no history of pneumonia, or pneumonia occurring after age five years. Gray line is locally weighted smoothing of participants marked with gray hollow circles. Maroon hollow circles mark participants with a history of pneumonia occurring at or before age five years. Maroon line is locally weighted smoothing of participants marked with maroon hollow circles. Age as marked on the horizontal axis indicates the age of the participant when lung function was performed.
