In plain language
In a single-center randomized study of 205 transradial coronary procedures, adding an under-table shield (curtain or drape) roughly tripled the reduction in operators' pelvic dose and halved thorax dose, with both shield types performing similarly.

What it found
Adjunctive under-table shields were associated with lower operator pelvic dose than no shield.
Key figures: 42 µSv [14-98] vs 13 µSv [5-27]; P<0.0001
Operator thorax dose was also lower with adjunctive shields.
Key figures: 4 µSv [1-13] vs 2 µSv [1-4]; P=0.001
Dose reduction was seen for every operator.
Key figures: 4 operators
A small curtain and a drape under the table gave similar pelvic doses.
Key figures: P=0.183
Limits to keep in mind
Single-center study with only 4 operators and transradial procedures only; dosimeter-measured dose rather than health outcomes, and country and dosimeter details are not stated in the abstract.
