The Effects of Atmospheric Pressure Fluctuations on Human Behaviour Related to Injury Occurrences: Study on the Background of Low and Moderate Levels of Geomagnetic Activity

Table 2

95% Confidence intervals (CI) for two categories of DHAI (low and high) values and corresponding EEI number for raw data (EEI/0), data adjusted for the four potential confounding variables (EEI/4), and then additionally adjusted for the DHAG (EEI/4G) (a) along with data on two categories of DHAG (low and high) values with corresponding EEI number for data adjusted for DHAI (EEI/I) and the five potential confounding variables including DHAI (EEI/4I) (b).

(a)
Parameter	Low DHAI CI (n1 = 254)	High DHAI CI (n2 = 91)	P value
DHAI (Pa)	1.81–2.00	5.15–5.85
EEI/0	3.83–4.48	4.81–5.95	0.0002
EEI/4	4.08–4.57	4.42–5.32	0.028
EEI/4G	4.10–4.57	4.42–5.28	0.032
(b)
Parameter	Low DHAG CI (n1 = 214)	High DHAG CI (n2 = 131)	P value
DHAG (Pa)	1.73–1.82	3.18–3.58
EEI/I	4.36–5.01	3.70–4.53	0.039
EEI/4I	4.37–4.89	3.86–4.54	0.032

P—significance of the difference in the EEI number between two categories (low and high) of DHAI and DHAG values.
