Query an OHDSI result table

Reads rows from a pre-computed OHDSI result table with server-controlled disclosure. When scope = "pooled", counts are summed across servers with suppression propagation; rates/proportions are set to NA.

Usage

ds.omop.ohdsi.results(
  table_name,
  columns = NULL,
  filters = NULL,
  order_by = NULL,
  limit = 5000L,
  tool_id = NULL,
  scope = c("per_site", "pooled"),
  pooling_policy = "strict",
  symbol = "omop",
  conns = NULL
)

Arguments

table_name

Character; which result table to query.

columns

Character vector; columns to select (NULL = all safe columns).

filters

Named list; WHERE conditions.

order_by

Character; ORDER BY column.

limit

Integer; max rows (capped at 5000 server-side).

tool_id

Character; optional tool identifier.

scope

Character; "per_site" or "pooled".

pooling_policy

Character; "strict" (default) or "pooled_only_ok".

symbol

Character; the session symbol (default: "omop").

conns

DSI connection object(s). If NULL, uses active session.

Value

A dsomop_result object.

Examples

if (FALSE) { # \dontrun{
# Cohort diagnostics results per site
cd <- ds.omop.ohdsi.results("index_event_breakdown")

# Cohort counts pooled across servers
cc <- ds.omop.ohdsi.results("cohort_count", scope = "pooled")
} # }
