Table 2 The results of Joinpoint Regression analyses on secular trends of urban and rural suicide rates

From: Suicide rates in China, 2004–2014: comparing data from two sample-based mortality surveillance systems

  Segment 1   Segment 2
APC (95% CI) JP (95% CI) APC (95% CI)
Urban
 CDC-DSP −9.0 (− 11.8, − 6.0) 2011 (2006, 2012) 3.0 (−8.7, 16.2)
 MOH-VR −4.3 (− 10.5, 2.4)   
Rural
 CDC-DSP −12.2 (− 18.0, −6.1) 2006 (2006, 2008) −4.3 (− 5.0, −3.5)
 MOH-VR − 2.2 (−3.9, − 0.5)   
  1. Summary of the Annual Percent Change (“APC”) in Crude Suicide Rates Joinpoints (“JP”s) on the trends in the urban and rural suicide rates and their 95% Confidence Intervals (“CI”s) using the data from the CDC-DSP and MOH-VR Systems (2004–2014). APC coefficients are the annual percent changes in suicide rates in the years between the specific joint points. Negative coefficient indicates downward trends; positive coefficient indicates upward trends. JPs are years when changes in suicide trends occur
