The reasons varied: fighting, smoking, testing positive for drugs; but often prisoners are sent into isolation for more serious crimes, like stabbing other inmates, trying to escape or attacking guards.
The primary aim of this study was to establish the optimal cut-off value for cotinine in saliva and urine of pregnant women in Poland and to compare the diagnostic effectiveness of three smoking tests: cotinine in saliva and in urine and in urine with creatinine correction.
Too few women smoked bidi smoking to test interactions between SES and gender for this outcome.
As observed earlier for blood, no significant influence of beryllium concentration in serum is attributed to sex or smoking (T-test, p > 0.05).
If the patient agrees, informed consent will be requested, and a series of tests will be indicated (spirometry, peak expiratory flow rate, smoking dependence test, smoking cessation motivation test and a structured questionnaire on sociodemographics data, history of disease, smoking habit, respiratory symptomatology, etc).
Multivariate models adjusting for sex, grade, socio-economic status, smoking status, test time and a test time-ad version interaction term were also run.
The funnel plots showed no evidence of publication bias among the included studies on passive smoking (Egger test, P = 0.166), but there might be publication bias among those on active smoking (Egger test, P = 0.001; Figure 2 ).
The effect modification by alcohol and cigarette smoking was tested with the heterogeneity test, while the attributable proportion (AP) was used to measure the biological interaction from the gene-gene interaction analysis.
