Video Versus Face-To-Face Preoperative Anaesthetic Assessment: The VIDFACE Trial-A Statistical Analysis Plan.
Trial report in Acta anaesthesiologica Scandinavica, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06765538 (Video Versus Face-to-face Preoperative Anaesthetic Assessment), which is not on this map. Cited by 2 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.

Abstract
backgroundThe video versus face-to-face preoperative anaesthetic assessment (VIDFACE) trial is a randomised, multicentre, two-arm, superiority, assessor- and data analyst blinded clinical trial. The routine use of preoperative assessments is accepted as the gold standard for elective surgery, reducing both morbidity and mortality. In recent years, video-based assessments have been investigated with a focus on patient satisfaction and enhancing efficacy. The VIDFACE trial aims to compare video-based preoperative anaesthetic assessment with face-to-face assessments, with a focus on patient safety and satisfaction.
objectiveTo report the statistical analysis plan for the VIDFACE randomised clinical trial. METHODS/
designWe will enrol 2260 adult participants undergoing elective ear-nose-throat or oral and maxillofacial surgery. Participants will be randomised 1:1 stratified by 'trial site' and 'known or suspected malignant/haematological condition' to either intervention (video-based preoperative anaesthetic assessment) or control (face-to-face preoperative anaesthetic assessment). Two blinded statisticians will analyse the data. Before unblinding, we will write two abstracts based on the initial blinded analysis, one assuming A is intervention and B is control and one with the opposite assumption. Primary outcome is a composite outcome including five predefined serious complications. We assume a 30% relative risk reduction of the primary composite outcome. An interim analysis will take place after inclusion and follow-up on half of the intended sample size.
conclusionThis statistical analysis plan of the VIDFACE trial will minimise analysis bias and add transparency to the statistics applied in the results of the trial.
