The Silent Operation Theatre Optimisation System (SOTOS
Trial report in Journal of robotic surgery, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
To reduce noise pollution and consequently stress during robot-assisted laparoscopic radical prostatectomy (RALP) the aim of our study was to evaluate the silent operation theatre optimisation system (SOTOS) in its effectiveness. In the operating room (OR) the noise level is between 80 and 85 decibel (dB). Noise corresponds to a major stress factor for surgical teams and especially surgeons. The use of the da Vinci surgical system entails an additional aspect of noise in the OR. The SOTOS surgical team used wired or wireless headphone/microphone combinations to communicate. We measured sound pressure levels in two different locations in the OR and the heart rate of every surgical team member as an indicator of the stress level. We further captured subjective acceptance of SOTOS as well as perioperative data such as surgical time. We prospectively randomised 32 RALP patients into two study arms. Sixteen surgeries were performed using SOTOS and 16 without (control). Overall, the mean sound pressure level in the SOTOS group was 3.6 dB lower compared to the control (p < 0.001). The highest sound pressure level measured was 96 dB in the control group. Mean heart rates were 81.3 beats/min for surgeons and 90.8 beats/min for circulating nurses. SOTOS had no statistically significant effect on mean heart rates of the operating team. Subjective acceptance of SOTO was high. Our prospective evaluation of SOTOS in RALP could show a significant noise reduction in the OR and a high acceptance by the surgical stuff.
