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

backgroundDuty hour restrictions have increased the role of simulation in surgical education. A simulation that recreates the unique visual, anatomic, and ergonomic challenges of anorectal surgery has yet to be described. The aim of this study was to develop a low-cost, low-fidelity anorectal surgery simulator and provide validity evidence for the model.

methodsA novel, low-fidelity simulator was constructed, and anorectal surgery workshops were implemented for general surgery interns at a single institution. Face and content validity were assessed with separate questionnaires using a 5-point Likert scale. Participants performed a simulated hemorrhoid excision with longitudinal wound closure, and transverse wound closure. Time-to-task completion and quality of suturing/knot tying were evaluated by a blinded observer to assess construct validity.

resultsMaterial cost was US $11 per simulator. We recruited 20 first-year surgery residents (novices) and 4 practicing colorectal surgeons (experts), and conducted 3 workshops in 2014-2016. All face and content validity measures achieved a median score greater than 4 (range 4.0-5.0). Time-to-task completion was significantly lower in the expert cohort (hemorrhoid excision with longitudinal wound closure: 195 vs. 477 s and transverse closure: 79 vs. 192 s, p < 0.001 for both). Suturing and knot-tying scores were significantly higher in the expert cohort for both tasks (p < 0.05 for all comparisons).

conclusionsOur low-fidelity, low-cost anorectal surgery model demonstrated evidence of face, content, and construct validity. We believe that this simulator could be a useful instrument in the education of junior surgical trainees and will allow residents to obtain proficiency in anorectal suturing tasks in conjunction with traditional surgical training.
