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: 136 cases, 77 expected
Factor (95% interval): 1.8× (1.5× to 2.1×)
Multiple testing: q = 0.0047 (Benjamini-Hochberg)
Second measurement: p < 0.001
Other comparison groups: economically active companies 2.6× (2.2× to 3.0×); all companies 3.5× (2.9× to 4.1×)
Absolute difference: 0.5 percentage points; following 194 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: shifted follow-up period, excluding cases within 60 days, negative control (outcome before the event), overlap of definitions, stability across measurements, E-value, three comparison groups. Not passed: placebo event.
