Forrest Plot not displaying data (PROC TEMPLATE)

KuldeepThakuri — Mon, 20 Jan 2020 05:36:03 GMT

Dear Community,

I created an input data set to produce a forrest plot (input data set attached as forrest.xlsx). The input dataset is in the exact format that I want my forrest plot to be. My code works as expected except that row number #22 (subgrp='Therapy*,' value '>=2') doesnt show up in the rtf output. The output is attached (forrest1.docx) and as you can see subgrp= ">=2"' doesnt show up in the rtf. When I dug further it seems like there is a tons of space between the row values. For example, when I run my code by restricting the input data for subgrp='Therapy*' only, my output looks like attached forrest2.docx.

Please advise

Below is my code:

(please note data final in proc sgrender is the forrest.xlsx dataset attached)

%let v21=20;
%let v22=70;
proc template;

Is it possible that the data values contain extra space characters? Sanjay discusses space characters in the context of Forest plots in this article.

Did you get the template from somewhere else? If so, please provide a link to the original source.

Hi Rick,

Thanks for the feed back. I have been using this program/template for a while w/o any issues until now. So I dont remember the source of it.

Anyways, I spent quite a few time with trial and error and found a solution in the format, which to me is really weird - something I am not understanding. Please let me know if you can help me understand it.

So , for the subgroup that I was having issue with, I had created a user defined formats. (I had done this for every subgroup in the table). Below is the format for the subgroup I am having issue with.

proc format;

value LINEPTXN 1= "1" 2= ">=2";

run;

With this format, I having the issue of category ">=2" not displaying in the rtf (attached as forrest1.docx in the original comment).

However, when I change the format to add a space before >=2, it works!

proc format;

value LINEPTXN 1= "1" 2= " >=2"; /*Please note a space before >= here vs the the first format w/o the space */

run;

Thanks,

Kuldeep

Be advised that the message windows on this forum strip out white space characters in many instances.

You need to post code containg spaces in a code box opened with the {i} other wise both of your example lines look like

value LINEPTXN 1= "1" 2= ">=2";

Example: In code box:

value LINEPTXN 1= "1" 2=     ">=2";
value LINEPTXN 1= "1" 2= ">=2";

without

value LINEPTXN 1= "1" 2= ">=2";
