Pairwise Comparison Summary Table

How to access pairwise comparison results in Licklider, what the table contains, and which analyses produce one.

When an analysis involves multiple group comparisons — such as a one-way ANOVA with post hoc tests — Licklider generates a pairwise comparison summary table alongside the figure. The table shows each pair of groups that was compared, the test result for each pair, and whether the comparison was statistically significant after correction for multiple testing.

Where to find it

The pairwise comparison table appears in the Table tab of the figure Inspector, in the Pairwise Comparisons section. This section only appears when pairwise comparisons were generated for the figure.

The Table tab may also contain a Baseline Characteristics section and a Statistical Results section. All three are in the same tab.

What it contains

Each row represents one pairwise comparison. Columns include:

  • The two group names being compared
  • p-value (unadjusted)
  • p-value adjusted for multiple comparisons
  • Whether the comparison is significant at the adjusted threshold
  • Mean difference between the two groups (where applicable)
  • Effect size
  • 95% confidence interval bounds

For two-way ANOVA, the factor being compared is also shown alongside each row.

Which analyses produce a pairwise table

Pairwise comparison tables are generated for the following analyses:

One-way ANOVA with post hoc

Pairwise comparisons for each pair of groups, using the post hoc correction method selected (Tukey HSD, Bonferroni, Holm, or Benjamini-Hochberg).

Two-way and three-way ANOVA

Pairwise comparisons within each factor level. For three-way ANOVA, the mean difference column is not populated.

Kruskal-Wallis and Friedman

Non-parametric pairwise comparisons derived from the significance analysis.

Kaplan-Meier survival analysis

Pairwise log-rank comparisons between survival curves when three or more groups are present.

When no pairwise table appears

If the analysis did not produce pairwise comparisons — for example, a two-group t-test or a single-group analysis — the Pairwise Comparisons section does not appear in the Table tab. No message is shown; the section is simply absent.

If the analysis should have produced pairwise comparisons but they are not available, the section will indicate that results are not available for this figure.

Downloading as CSV

A download button in the Pairwise Comparisons section saves the table as a CSV file.
