1 · What the graph read from it

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.

2 · The registry

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

objectiveWe sought to validate a laryngeal simulation model and subsequently demonstrate its efficacy in improving surgical technique. STUDY

designPre-post interventional study.

settingOtolaryngology Program at a Tertiary Care Center.

methodsA low-cost, high-fidelity laryngeal model was created using a 3-dimensional-printed cast and multilayered silicone to mimic vocal fold lesions. Participants (attendings and trainees) were first given a series of tasks including mucosal vocal fold lesion resection and microflap excision of a submucosal lesion. Trainees were then provided with an instructional video from a laryngologist and asked to repeat the same tasks on the model. Performance data was then assessed using validated surveys and blinded expert reviewers.

resultsEighteen participants completed the simulation. All subjects agreed that the "simulation experience was useful" and 93% agreed "the simulator helped improve my ability to do microsurgical tasks." In the postinstruction self-evaluation, trainees reported a significant decrease in mental demand (95% confidence interval [CI]: 0.37-0.91; P = .038) and significant increase in subjective performance (95% CI: 1.51-51.89; P = .016) compared to the preinstruction self-evaluation. On the postinstruction attempt, there was a significant improvement in all domains of the adapted objective structured assessment of technical skills as measured by 3 blinded, expert reviewers. DISCUSSION: This study demonstrates the usefulness of a silicone larynx model and the value of instructional video in developing laryngeal microsurgical skills. Participants positively reviewed the laryngeal model and trainees saw both a subjective and objective improvement indicating tangible operative benefits from the use of this laryngeal simulation.
