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

Objectives: Ventilation of bearded patients using the standard face mask (FM) is often difficult, particularly in field settings and mass casualty events. The current study compares the effectiveness of a novel Bag-Valve-Guedel Adaptor (BVGA) with the standard FM when applied to anesthetized patients by anesthesiology trainees with limited experience. Methods: Male patients scheduled for elective surgery (American Society of Anesthesiology physical score 1-2) were recruited for this prospective, randomized, cross-over trial. Beard length was categorized as <0.5 cm (none/stubble), 0.5 to 1 cm, 1 to 5 cm, or ≥5 cm. Anesthetized patients were ventilated by anesthesiology trainees using the BVGA and an FM. The main outcome included end-tidal CO Results: Forty men (mean ± SD, age, 37 ± 17 years; body mass index, 25 ± 3 kg/m Conclusion: The BVGA provides more effective and convenient ventilation than the FM for ventilation even when applied by anesthesia trainees. Its use can be of particular value in bearded subjects or in a setting where the use of supraglottic airway devices is limited.
