Graphing results of outcome analysis showing CIs
Hi Does anyone have a tip for the best and easiest way to graph the results of the attack rate table for an outbreak analysis including confidence intervals? I have run the outbreak analysis and generated the attack rate table (TAB CASE 1 OYSTERS PRAWNS CHICKEN etc OA/ex), This is great. BUT...
Now I have been asked to show all the exposures with relative risks higher than 2 and CIs that don't include 1 (of which there are about 10) on a single graph. The graph must show relative risk, lower confidence interval and higher confidence interval for each exposure. I have looked at the CI graph in Epidata Analysis but a) I only want the total and the CIPLOT graph shows Yes and No as well as total b) I want to show more than one exposure on the same graph and I don't think I can do this with the CI.
Any help much appreciated.
thanks

As indicated by Christine this is not possible just now, but there is a "work around".
task: Show proportion of cases among those exposed to a number of exposures, e.g. OYSTERS PRAWNS CHICKEN in a graph. But DO NOT show among those in each individual exposure NOT exposed.
1. Create a standard ci plot ciplot case OYSTERS PRAWNS CHICKEN /notot (notot if you wish to exclude the overall)
2. Paste into a graphing or word processor immediately after creating the graph (shift to that other software and press - ctrl+V) Do not rigth click on graph and copy - this will create a bmp file.
3. Edit graph in that software a Here you would delete the parts of the ciplot shown for "non exposed" to each exposure. b create a "nice" x-axis indicating the 10 exposures.
4. If you cannot do point 2-3 due to problems create a "BMP" by right clicking on the graph and paste into a drawing software, e.g. GLIMP. Then use an erase or white pencil and move those parts not desired.

Hi Christine,
CIPLOT is showing proportions, not RR. I think you will have to create your own chart in another package. You can import the attack rate table into excel and with a bit of manipulation, get the columns in the right order for a "stock chart" - stock chart uses the order Close, High, Low, where Close will be RR, High will be UCL and Low will be LCL.
However, you will have to do some formatting to do to get the chart looking as good as CIPLOT.
