As outlined in Figure 2 , there was a strong trend towards salt and sodium reduction in breakfast cereals, with nine of the eleven studies included reporting a reduction in salt or sodium content of breakfast cereals.

Even in major producing areas, the proportion of non-grain production is shown to have an increasing trend [ 18 ].

Among them, D2 has a moderately significant spillover effect across the basin due to the insignificance of the upper reaches, suggesting that the disposable income of residents in Western China is more influential than S4 and R6 in driving the spatial evolution pattern of tourism eco-security across the basin.

A positive AAPC indicated an increasing trend and vice versa [ 17 ].

Between 2000 and 2019, 31 provinces showed only decreasing trends in mortality rate, while Hong Kong and Macau had a single joinpoint, with an increasing or stable trend followed by a decreasing trend in under-5 LRI mortality rate ( Supplement Figure S1 ). 3.3.

Judging from the current situation, the two-week prevalence rate of rural residents in China increased from 20.2% in 2013 to 32.2% in 2018, which means that the overall health status of rural residents in China is on a decreasing trend.

Specifically, the statistics of the first-order serial correlation test, AR (1), were highly significant, while the statistics of the second-order serial correlation test, AR (2), were insignificant, which implied that the results were affected by first-order autocorrelation but not affected by second-order autocorrelation.

Spatially, more than half of the vegetation NEP (60.61%) in NXJ showed an increasing trend, 5.46% and 41.01% of the area showed a significant or extremely significant increasing trend.

Spatially, NXJ’ NEP showed a decreasing trend (−0.73 gC m −2 yr −1 ), whereas the vegetation NEP in SXJ and HX showed an increasing trend, with rates rising by 0.60 and 0.13 gC m −2 yr −1 , respectively ( Figure 3 b).

The vegetation NEP in the mountain exhibited only intermittent changes (2.55 gC m −2 yr −1 ) during 2000–2020; it exhibited a negative trend during 2000–2010, but this trend has reversed strongly since 2010.

The vegetation NEP in the plains exhibited a positive trend (1.21 gC m −2 yr −1 ) during 2000–2020, but this speed has slowed since 2010.

in the diatom phyla in the whole sample showed a trend of increasing relative cell density along the gradient to the flow velocity.

Around the middle reaches and downstream of the YRB showed a decreasing trend.

Among older females, the numbers were even higher, with 5.32 cases in 2015, followed by an increasing trend toward 7.59 cases in 2019.

A stable trend was observed for younger workers, while a positive trend was observed for older workers in the form of a decrease in MSD-related SL.

The regression results once more prove the previous research conclusion that energy use right trading has a highly significant impact on environmental performance.

From 2000 to 2017, the cultivated land in the tourist areas showed a trend of first increasing and then continuously decreasing.

In general, the mean values for the CVQ-96 scores indicated a decreasing trend by grade, which means that students from higher grades reported lower scores.

The difference between men and women is noteworthy in perceived infectability in the age range of 18 to 21 years old, highly significant and with a large effect size.

It is the first and most highly significant policy document since it outlines the purpose “to reduce consumption of alcohol, availability, especially to minors, alcohol abuse, the damage caused by it to health and the economy and to establish legal principles of granting economic entities the right to manufacture, sell, import and export alcohol products.” Initially, policy implementation of the law was delegated to the ministries, and then one year later, from 20 June 1996, to a newly established supervisory body: the State Agency for Tobacco and Alcohol Control [ 17 ].

Linear regression analysis was used to establish whether possibly significant effects due to differences in age, gender, and marital status were missed.

[ 22 ] found that precipitation exhibited an increasing trend in the west part of China but decreasing trend in east part of China from 1960 to 2012.

For the heavy precipitation days, 49.51% of stations showed positive trends, and a significant trend was only found at one station.
