Copy Table 1
Paste into Word as a formatted table, or download a CSV.

What goes in Table 1

Table 1 describes the baseline demographic and clinical characteristics of each study group. Both CONSORT (for randomized trials) and STROBE (for observational studies) ask authors to report these characteristics.

Use mean (SD) for roughly symmetric continuous variables and median [IQR] for skewed ones, and number (%) for categories. Report missing data.

In randomized trials, the CONSORT explanation calls significance tests of baseline differences superfluous, because any differences between randomized groups are due to chance. p-values are hidden by default for that reason; you can show them for observational comparisons.

How it is calculated

Continuous: mean (SD) or median [IQR]; categorical: n (%) of non-missing values
Optional p-values: Welch t-test or one-way ANOVA (means), Mann-Whitney or Kruskal-Wallis (medians), chi-square test or Fisher's exact test for 2×2 tables with an expected count below 5

Table 1 Generator: FAQ

Should I include p-values in Table 1 of a randomized trial?

Generally no. CONSORT explains that such tests are superfluous in randomized trials; describe the groups instead.
