§1How it’s measured

This is a behavioral construct — an event recorded in HR systems, not a self-report. It is measured as an operational metric with a formula, not a questionnaire; a Likert scale here would be a category error.

Safety and Health Metrics (LTIFR)behavioralorganization
The frequency of lost-time work-related injuries per million hours worked, capturing workplace safety performance.
LTIFR = (Number of lost-time injuries / Total hours worked) * 1,000,000 · rate
Safety Incident Countbehavioralunit
The number of recordable safety incidents, including OSHA recordables and near misses, over a period.
Count of recordable safety incidents in period · count
Safety Incident Ratebehavioralunit
Recordable safety incidents per exposure hours.
incidents × 200,000 / hours worked · rate

§3The math on what we know

Synthesized priors from the live registry: pooled r, studies (k), total N, top study grade, and heterogeneity. Rows flagged for heterogeneity or single-study evidence are directional, not settled — read them as a central tendency.
