Exceptions included suicide and self harm at three and nine months and all cause mortality at six months in the bupropion group compared with nicotine replacement therapy, where the instrumental variable analyses showed a reduced risk (web appendix F).
When the high-Depersonalisation group was compared to a random similar-sized group of staff with the lowest ratings on this variable, univariate analyses showed that high depersonalization-scorers were younger, more of them lacked professional qualifications of any sort and the majority came from one of the centres.
Though there were missing observations of some variables, our analyses showed that the missing observations did not significantly influence the findings of the study.
After controlling for the relevant variables, hierarchical regression analyses showed that the personality variables explained 16.2% of the variance in sleep-related dayshift tolerance, 12.2% of the variance in sleep-related evening shift tolerance and 20.7% of the variance in sleep-related night shift tolerance.
Variable temperature crystallographic analyses showed that for KC1 these transitions were associated with changes in crystal packing from orthorhombic to monoclinic: phase I (428 K) to phase II (349 K) [131].
However, variable temperature infrared analyses showed an increase in the stretching frequencies of the CH2 group as a result of disordering of the alkyl chains in the mesophase [167] in agreement with dilatometric and 1H-NMR studies [170].
Self-reported age was included in the regression as the controlling variable because earlier analyses show that increasing age significantly contributes to job satisfaction [ 32].
Controlling for a number of other variables, we conducted analyses showing that the probability of a pitcher hitting a batter increases sharply at high temperatures when more of the pitcher's teammates have been hit by the opposing team earlier in the game.
The results of the multi-variable analyses are shown in table 2. The presence of a person with respiratory disease in the home, the belief that pollution is harmful, occupational class, home ownership and reporting noise and other peoples smoking as problems were all very strongly and independently associated (<0.001) with reporting behaviour.
Co-occurrence analyses showed variable support for community assembly rules.
