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.

|---|---|
| Prevalence >40% | |
| 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) |
| Prevalence 10%–19% | |
| Current smoking | −2.80 (−5.47 to −0.21) |
| Depression | 1.20 (−1.05 to 3.48) |
| Diabetes | −0.10 (−2.02 to 1.83) |
| Prevalence <10% | |
| Extreme obesity | −1.60 (−2.95 to −0.27) |
