Figures & data
Figure 1. This flow diagram provides a description of the overall ODSS linkage process. A total of 7240 paramedics were identified in the Workplace Insurance & Safety Board (WSIB) claims data from 1996 to 2019 and incidence of cancer among paramedics were identified through the Ontario Cancer Registry (OCR).

Table 2. Hazard ratios and corresponding 95% confidence intervals for risk of cancer among paramedics compared to all other workers in the ODSS cohort.
Figure 2. Risk estimates (HRs) and corresponding confidence intervals (95% CI) for selected cancers among paramedics in the Occupational Disease Surveillance System cohort are shown, in comparison to police and firefighters in the same ODSS cohort reported in a previous publication (Citation8). The ODSS was established by linking accepted lost-time claimants from the Workplace Insurance & Safety Board (WSIB) to various databases such as the Ontario Cancer Registry (OCR). Occupation was reported at the time of the claim in the WSIB data and was coded using various coding systems. Paramedics were coded using the National Occupational Classification (NOC) system and police and firefighters were coded using the Canadian Classification Dictionary of Occupation (CCDO) system in WSIB data. Incident cancer cases were identified through the Ontario Cancer Registry (OCR) and coded using the International Classification of Diseases 10th Revision (ICD-10).
