The regression coefficients represent the difference in days relative to the number of days for the workers without GRTW by 10 percentiles of the distribution.
*Adjusted for: MSD, age, wage, gender, occupation, prior claims, firm size, industry sector, claim year, use of opioids, NSAIDs and SMRs within 30 days post claim.
†Adjusted prediction of cumulative time-loss days when all other variables are set at the sample means.
‡Zero value caused by censoring of the data at 365 days.
GRTW, gradual return to work; MSD, musculoskeletal disorder; NSAIDs, non-steroidal anti-inflammatory drugs; RTW, return to work.
