To the Editor A recent Research Letter1 examined temperatures generated with temporal artery thermometers with the goal of identifying systemic bias in medical devices. As one of us (F.P.) is the inventor of the temporal artery thermometer, and as we are scientists working for its manufacturer, we wish to highlight that this study showed that Black and White patients had essentially the same fever rates and temporal temperatures (eg, 38 °C: 10.1% vs 10.8% [P = .49]; mean, 36.98 °C vs 36.97 °C [P = .67]).1
