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
Preoxygenation can rapidly improve oxygenation and enhance the security of endotracheal intubation, so it is very essential before endotracheal intubation. The conventional preoxygenation method self-inflating bag (SIB) is not very effective in case of emergency. So our study aims to find a more effective method of preoxygenation in a critical situation.We retrospectively analyzed data of 105 patients in this study. A total of 49 patients with preoxygenation with invasive ventilator in volume control mode (VCM) and 56 patients with preoxygenation with SIB were included. No significant differences were detected in the baseline data of the 2 groups (P > 0.05). Time of preoxygenation (95%) was 174 (168-180) seconds in group VCM and 205 (199-212) seconds in group SIB (P < 0.05), and multifactor linear regression showed that its main risk factors were the methods of preoxygenation and PO2 before preoxygenation (P < 0.05). Immediate SPO2 after preoxygenation was 91 (89-92)% in group VCM and 85 (83-86)% in group SIB (P < 0.05). Total time of preoxygenation and intubation was 266 (252-280) seconds in group VCM and 318 (298-338) seconds in group SIB (P < 0.05). The 24-hour and overall survival rate in group SIB were lower than in group VCM (P > 0.05). Cox regression showed that SaO2 at 5 minutes after intubation was the major risk factor for the survival rate.Invasive ventilator with volume control mode can shorten the time of preoxygenation and improve the quality of preoxygenation in patients with emergency intubation and may be a better method of preoxygenation in a critical situation.
