The predictive model of osteoarthritis (Additional file 3 ) confirms age as a determinant of this condition, with the eldest age group showing a significantly increased risk (RR = 2.98 (1.49, 5.93)) (and a strong trend in the 55–64 age group).
However, parish of birth approached significance as a predictor of CVD in later life, and this is likely to reflect residual differences in social class related to the higher proportion of non-manual paternal occupations in urban parishes [ 28 ].
Results Descriptive characteristics of pulmonary tuberculosis cases A total of 38,667 pulmonary tuberculosis cases were reported in the Jining city, Shandong provinces of China from 2009 to 2022, showing a decreasing trend yearly ( Table 1 ) .
Currently, three serotypes (DENV1, 2 and 3) co-circulate in most areas of Brazil and an increasing trend in hospitalization rates has been observed, suggesting a shift in disease severity [ 18 ].
In this regard, although the overall trend observed was quite significant, it was only women with a high school or above education that ended up with a low risk of having high fertility compared to those without modern education (OR = 0.37, 95% CI: 0.21, 0.64).
The former was positively associated with number of recent sex partners for males (IRR = 1.53, 95%CI: 1.07 – 2.18), while the latter was marginally significant for females (IRR = 1.92, 95%CI: 0.97 – 3.79).
The participants covered by health insurance had 1.6 times greater odds of healthcare utilization than did those without health insurance (95% CI = 0.99–2.58) with marginal significance.
On the other hand, some of those substances that had a decreasing trend in prevalence either exhibited an increasing trend (e.g., alcohol and tobacco), remained relatively stable (e.g., ecstasy for middle school students) or, to a lesser extent, decreased in onset rate (ecstasy, ketamine, and marijuana for high school students).
Results For middle school students (grades 7 and 9), a decreasing trend in lifetime use prevalence over the years was found in tobacco, betel nut, ecstasy, and GHB (Additional file 1 : Table 1, upper panel).
The mother's marital status was borderline significant in the crude analysis, with a two-fold increase in odds ratio for being stunted if the mother was single, divorced, separated or widowed.
The Theil index of the number of institutions shows a decreasing trend, indicating that the equity of the number of institutions is gradually improving.
Parental smoking at the time of interview was only marginally significant; however, when restricted to daily smokers, it remained significant in the multivariable model (data not shown).
However, the effect of low educational attainment is close to being statistically significant and we argue that this suggests that there are effects of educational attainment and the risk of ME/CFS, even when comparing with a population that innately controls for the effect of educational attainment on the likelihood of hospital diagnosis.
