Atlas Incidence Rate: "one criterion failed"

Hello.

I’m plating a little bit with Atlas and I have calculated the IR from one target cohort to an outcome cohort.

And I get this:

What is that “1 criteria falied”?
How can I know what criteria has failed?

Regards

Your screenshot is now showing the content under the ‘stratify rule’ table…do you have any stratification in this IR? Can you post the screenshot but include the entire report?

Here you have.

Today it works well, or I have done something different.

And now I can see that “1 criteria failed” just means that the chosen square represents people meeting all all but one criteria.

Ok, thanks, makes sense. Here is what is happening:

The left side (the table) shows each strata you defined and the counts in each row of the table are those people that satisfied the rule for the row. So, your Females were N=24,257 with 302 cases, your Males were N=16,674 with 384 cases. Each rows has cases, time at risk and therefore a rate.

Turning attention to the right side (the visualization), we perform the analysis and group people into their combination of the strata that they satisfy. You have mutually exclusive strata (you are either male or female, you are either age < 50 or > 50. But the combos that are possible are:

  • Male < 50
  • Male > 50
  • Female < 50
  • Female > 50

The box on the right shows the N and TAR for each combination that exists in your analysis. By hovering over the boxes you can see what it represents by looking at the ‘criteria passed’ which is the non-red highlighted rows in the table when you select/hover over a box.

The example you gave was those poeple who are "Not Female (red), Male (black), Not Age < 50 (red), Not Age > 50). Ie: 1 criteria passed, 3 failed. Why do you have a box where people are both not < 50 and not > 50? Those are the people who are 50! So that box represents the 50 year-old men in your analysis.

I’m guessing you didn’t mean to do that and you wanted the age groups to be ‘less than 50’ and ‘greater than or equal to 50’…so if you want to get rid of that box, just adjust your age strata to be <=50 and > 50 or < 50 and >= 50.
