Question

Generally, a 2x2 table is arranged with the ______  in the rows and the _______ in the columns.

BlackTom AI · Accepted Answer

When constructing a standard 2x2 epidemiologic table, the placement of variables follows a conventional pattern that helps interpret relationships clearly.
Option 1: 'margins; cells' is incorrect because margins and cells refer to the outer totals and the interior counts, not to the primary row/column structure that distinguishes exposure from disease status.
Option 2: 'disease status; exposure status' reverses the typical arrangement; placing disease status in the rows and exposure status in the columns is not the common convention used in standard 2x2 tables for exposure-disease analyses.
Option 3: 'cells; margins' swaps the focus from the variable layout (rows and columns) to the interior counts versus margins, which does not specify how to organize the variables themselves in rows and columns.
Option 4: 'exposure status; disease status' correctly identifies the usual setup, with exposure status (e.g., exposed vs unexposed) placed in the rows and disease status (e.g., diseased vs not diseased) placed in the columns, aligning with common epidemiologic reporting and interpretation.
