Table 4.
Estimated Risk Ratios (RR) for reported occupational injuries and confirmed dehydration cases among sugarcane harvesters in Southwestern Guatemala—2014–2018. All models adjusted for total number of workers and harvest season.

| Average daily tons cut | 1.09 (0.89, 1.32) | 0.404 | 1.17 (0.94, 1.45) | 0.160 | 1.00 (0.61, 1.62) | 0.999 |
| Acclimatization period 4 | 1.17 (0.64, 1.99) | 0.584 | 1.31 (0.68, 2.29) | 0.385 | 0.85 (0.13, 3.36) | 0.835 |
1 All recorded occupational injuries to include: falls, hit by a falling object, slips, caught or stuck between an object, strains or sprains, exposure to extreme heat (non-ambient such as steam), exposure to electrical current, exposure to a harmful substance or radiation, chemical accidents, cut with an agricultural tool, vehicular accidents, bites from snakes or insects, agricultural incidents, or other. 2 Data only collected for 2016–2017 and 2017–2018 harvests. 3 WBGTmean was centered on 30 °C. 4 Acclimatization period occurred during the first 2 weeks of every harvest.
