Display top N most frequent records in chart

[jmalenfant]

Hi all - I'm trying to do something that I assume is a simple calculation that I'm struggling with for some time now.

Goal: display only the records that appear more than 2 times in a dataset.

Example of data:

TableID	ICD-9 Code	Patient ID	Visit ID
1	250	1	A
2	250	2	B
3	250	3	C
4	19	4	D
5	493	5	E
6	493	6	F
7	150	5	G
9	493	8	H
10	493	8	I

I'd like to produce a list of all ICD-9 codes that appear more than 2 (or any #) of times in the data, including both the ICD-9 Code value and the count of how many times this unique code appeared

Example output

ICD-9 Code	# of times the code was found in data (must be at least 2 times)
250	3
493	4

I've tried a few versions of this but can't seem to get it right

count( DISTINCT {<DX ={"=count(DX)>100"}>}DX), DX

If(Rank(Count(DISTINCT DX)) >100, Count(DISTINCT DX))

Thanks in advance!

Try this

Dimension

ICD-9 Code

Expression

Count({<[ICD-9 Code] = {"=Count(DX) >= 2"}>}DX)

Create a Straight/Pivot Table

Dimension

[ICD-9 Code]

Expression

Count(Distinct{<[ICD-9 Code] = {"=COUNT(Distinct TableID) > 2"}>}TableID)

Or

Count({<[ICD-9 Code] = {"=COUNT([ICD-9 Code]) > 2"}>}[ICD-9 Code])

Thanks so much - I knew it had to be something simple!
