The observed association between NO and TIA and minor stroke could be attributed to chance, due to multiple testing undertaken in the study.
In Liverpool, there was no significant positive association between TIA and minor stroke and any of the pollutants, but negative association were observed with PM10 and NO at lag 0 and 3 respectively.
Key income (in HK$): chronic conditions: 6: > 40000 B-musculoskeletal 5: 30000 - 40000 C - heart disease 4: 20000 - 30000 D - diabetes 3: 10000 - 20000 E - hyperthyroidism 2: 5000 - 10000 H - hypertension 1: < 5000 R - respiratory problems NA: refused to answer S - minor stroke All interviews were carried out between September 2007 and March 2008.
For Manchester data, a statistically significant positive association was observed between NO and TIA and minor stroke for lag 3 with estimated OR of 1.06 (95% CI: 1.01-1.11%).
A statistically significant association between the occurrence of TIA and minor stroke and exposure to NO with a 3-day lag was observed for the Manchester dataset.
Our simulation model distinguished between seven permanent health states, namely TIA, minor stroke, major stroke, recurrent minor or major stroke, ICH and death.
Our data suggest an association between NO and occurrence of TIA and minor stroke in Greater Manchester.
Given the recommendations of the national stroke strategy 7 and NICE guidance 8 that patients with TIA or minor stroke be assessed and treated urgently, we examined the relation between practice opening hours and delay to access healthcare in a population based study of all TIA and minor strokes, irrespective of age, and also determined the possible effect of the introduction of the new contract.
To explore the relationship between each ambient air pollutant and TIA or minor stroke, conditional logistic regression analysis was performed.
Briefly, 709 patients with incident TIA or minor stroke were prospectively recruited from TIA services in North West England between 2003 and 2007.
