A 10-year time-series analysis of respiratory and cardiovascular morbidity in Nicosia, Cyprus: the effect of short-term changes in air pollution and dust storms

Table 2 Percentage increase (and 95% CI) in admissions after adjusting for long- and short-term patterns as well as the effect of weather per 10 μg/m³ increase in PM₁₀ and 10 ppb increase in O₃ concentrations in Nicosia Central.

Notes: ¹ After restricting the analyses to Nicosia residents. ² Only aggregate numbers of all-cause admissions were available, thus it was not possible to restrict numbers to Nicosia residents. ³ Only includes people of adult age (15+) due to the rarity of cardiovascular events in those aged less than 15. ⁴ Restricted to days with daily average < 150 μg/m³. ⁵ Only the lag (lag 0 = same day or lag 1, 2 = previous two days) with the strongest positive association is shown.
