Pooled temperature-mortality association by latitude in 10 regions of England and Wales, 1993–2006. Predictions for the 25th (dot-dashed line) and 75th (dashed line) percentiles of latitude from meta-regression for overall cumulative summary (top panel), and predictor-specific summaries at 22°C (bottom-left panel) and 0°C (bottom-right panel). Reference at 17°C. The 95%CI are reported as shaded areas.
