Caveat The absolute difference is small, even though the factor is high. A common cause, such as growth, a takeover or a restructuring, may explain both. The outcome may be spotted more often at companies with the event. Read the title as an association, not as a cause.

Does it hold up?

Each measurement uses different companies and a different period. A link only counts if it shows up in both.

When does it happen?

Cumulative share by month after the first event. Half of the cases in the first year occur within 6 months.

Methodology

Design: Retrospective cohort study
Population studied: 1,141,228 Belgian companies (the full business register)
Comparison group: Companies without the event that had another publication or event in the same entry period (active group), from the same stratum: NACE section, size class and age class; indirect standardisation
Cohorts: event Feb–Jun 2025, outcome Jul 2025–Mar 2026; event Jul–Dec 2025, outcome Jan–Sep 2026
Observed and expected: 902 cases, 511 expected
Factor (95% interval): 1.8× (1.7× to 1.9×)
Multiple testing: q < 0.001 (Benjamini-Hochberg)
Second measurement: p < 0.001
Other comparison groups: economically active companies 2.3× (2.1× to 2.4×); all companies 2.9× (2.7× to 3.1×)
Absolute difference: 0.5 percentage points; following 220 companies with the event yields one extra case
Size of the groups: active 120,261, economically active 370,738, all 1,141,228 companies
Strata: 131 strata of at least 300 companies (section × size × age; smaller strata merged)
Review: Tests passed: excluding cases within 60 days, shifted follow-up period, negative control (outcome before the event), overlap of definitions, stability across measurements, excluding the largest stratum, E-value. Not passed: placebo event.
Data up to: September 2026
