Table 4 Odds ratios (ORs) and 95% confidence intervals (CIs) for subclinical carotid atherosclerosis based on platelet level

From: Association between tongue pressure and subclinical carotid atherosclerosis in relation to platelet levels in hypertensive elderly men: a cross-sectional study

  Tongue pressure p for trend 1 SD increment in tongue pressure
T1 (low) T2 T3 (high)
Lower platelet count
 No. at risk 55 64 52   
 No. of cases (percentage) 24 (43.6) 19 (29.7) 10 (19.2)   
 Crude ORs 1 0.55 (0.26, 1.16) 0.31 (0.13, 0.74) 0.007 0.55 (0.38, 0.81)

 Multivariable ORs 1 0.61 (0.26, 1.44) 0.35 (0.13, 0.91) 0.031 0.54 (0.35, 0.85)
Higher platelet count
 No. at risk 58 51 62   
 No. of cases (percentage) 18 (31.0) 14 (27.5) 14 (22.6)   
 Crude ORs 1 0.84 (0.37, 1.93) 0.65 (0.29, 1.46) 0.297 0.99 (0.72, 1.35)
 Age-adjusted ORs 1 1.05 (0.44, 2.51) 1.10 (0.44, 2.79) 0.834 1.27 (0.88, 1.83)
 Multivariable ORs 1 0.92 (0.37, 2.30) 1.11 (0.42, 2.29) 0.846 1.31 (0.87, 1.96)
  1. Multivariable ORs: adjusted further for age, systolic blood pressure, antihypertensive medication use, body mass index, smoking status, alcohol intake, serum triglycerides, serum HDL-cholesterol, antilipidemic medication use, HbA1c, and eGFR. Tongue pressure level tertiles: < 28.7 kPa, 28.7–36.4 kPa, and > 36.4 kPa. Lower platelet count is defined as < 21.4 × 104/μL. Subclinical carotid atherosclerosis is defined as a carotid intima-media thickness ≥ 1.1 mm. SD standard deviation. A 1 SD increment in tongue pressure is 10.4 kPa
