Table 1 Odds ratios for a traffic accident for Toxoplasma-infected subjects

From: Increased risk of traffic accidents in subjects with latent toxoplasmosis: a retrospective case-control study

Subset N victims N controls Odds Ratio C.I.(95%) P
15–29 years 59 [21, 35.6%] 249 [38, 15.3%] 3.07 1.63–5.79 <0.001
30–44 years 25 [9, 36.0%] 67 [15, 22.4%] 1.95 0.72–5.29 0.190
45–59 years 39 [17, 43.6%] 90 [22, 24.4%] 2.39 1.08–5.29 0.032
60–70 years 23 [11, 47.8%] 40 [9, 22.5%] 3.16 1.05–9.53 0.041
Total 146 [58, 39.7%] 446 [84, 18.8%] 2.65 1.76–4.01 <0.001
Men 85 [30, 35.3%] 230 [39, 16.9%] 2.71 1.54–4.79 <0.001
Women 61 [28, 45.9%] 216 [45, 20.8%] 2.68 1.43–5.02 0.002
Drivers 90 [35, 38.9%] 446* [84, 18.8%] 2.75 1.68–4.48 <0.001
Pedestrians 56 [23, 41.1%] 446* [84, 18.8%] 2.57 1.39–4.78 0.003
  1. * We used all 446 subjects as controls in the marked tests, as no information was available on the driver/pedestrian status of subjects in the control set. It seems reasonable to suppose that prevalence of latent toxoplasmosis is similar in pedestrians and drivers in the control set. Odds ratios (ORs), i.e., the odds in favour of traffic accident for the Toxoplasma-infected subjects divided by the odds in favour of traffic accident for the Toxoplasma-negative subjects, are listed for particular age strata; Mantel-Haenszel inferences of a common OR estimate (taking into account age-stratification of the data) are listed for other categories of subjects. The numbers in brackets in columns 2 and 3 show the number (and percentage) of Toxoplasma-positive subjects. All p-values are given for two-tailed tests.
