This is a scatter diagram entitled "Regression of Year on Log odds ratio". The horizontal axis shows year and has scale marked 1996.60, 1998.22, 1999.54, 2000.86, 2002.18, 2003.50, 2004.82, 2006.14, 2007.46, 2008.78, and 2010.10. The vertical axis shows Log odds ratio and has scale marked from minus 4.00 to 2.00 in intervals of 0.6.

There are 9 points at year = 1998, log odds ratio = minus 3.1, year = 2001, log odds ratio = minus 1.1, year = 2001, log odds ratio = 0.0, year = 2001, log odds ratio = 1.2, year = 2004, log odds ratio = 0.1, year = 2006, log odds ratio = minus 1.0, year = 2006, log odds ratio = minus 0.2, year = 2007, log odds ratio = 1.2, year = 2009, log odds ratio = minus 0.6.

The points are plotted as circles of diameter about 0.4 on the log odds scale.

There is a regression line from year = 1997, log odds ratio = 0.1, to year = 2010, log odds ratio = minus 0.4.
