In plain language
Across 643 coronary angiograms, circulating nurses' measured radiation doses were higher when patients had higher body mass index (BMI), about four times higher for BMI 40 or above than under 25, although per-procedure doses were small.

What it found
Patient BMI ≥40 was associated with a 4.0-fold higher nurse radiation dose than BMI <25.
Key figures: BMI < 25: 0.3 [0.1, 1.3] μSv; BMI ≥ 40: 1.2 [0.2, 2.9] μSv; p = 0.003
Each 1 kg/m2 increase in patient BMI was independently associated with a 3.3% increase in nurse dose on multiple regression.
Key figures: 3.3% per 1 kg/m2 (p = 0.002)
Patient dose (DAP) rose across BMI categories, 2.3-fold higher at BMI ≥40 versus <25.
Key figures: 2.3-fold (p < 0.001)
Nurse radiation doses differed significantly across patient BMI categories.
Key figures: p = 0.036
Limits to keep in mind
Observational dosimetry study from consecutive procedures, likely at a single centre, with only an abstract available; absolute nurse doses were very small (microsieverts) and the details of shielding use and dosimeter placement were not reported.
