This query is used to to provide summary statistics for condition occurrence counts (condition_occurrence_count) across all condition era records: the mean, the standard deviation, the minimum, the 25th percentile, the median, the 75th percentile, the maximum and the number of missing values. No input is required for this query.
Input:
<None>
Sample query run:
The following is a sample run of the query. The input parameters are highlighted in blue
SELECT condition_concept_id
, min( condition_occurrence_count ) AS min
, max( condition_occurrence_count ) AS max
, round( avg( condition_occurrence_count ), 2 ) AS avg
, round( stdDev( condition_occurrence_count ) ) AS stdDev
, PERCENTILE_DISC(0.25) WITHIN GROUP( ORDER BY condition_occurrence_count )
