Figure.
Prevalence estimates with 90% confidence intervals computed by using 3 TOST margins: ±2.5 percentage points (short dashed lines), ±5.0 percentage points (long dashed lines), and ±7.5 percentage points (medium-dashed lines). Health indicators are ordered in magnitude of prevalence in NYC HANES. Abbreviations: CHS, Community Health Survey; NYC HANES, New York City Health and Nutrition Examination Survey; TOST, two one-sided t test.

| Overweight/obesity | −8.60 (−11.47 to −5.66) |
| Influenza vaccination | −0.40 (−3.73 to 3.01) |
| Hyperlipidemia | 0.90 (−3.17 to 5.00) |
| Prevalence 20%–40% | |
| Hypertension | −0.90 (−3.78 to 1.97) |
| Obesity | −6.50 (−9.26 to −3.81) |
