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
Background: Laryngoscopy and tracheal intubation lead to an increased sympathetic reflex response, which is associated with increased heart rate and blood pressure. This response can be detrimental in patients with myocardial ischemia. This study aimed to investigate the effects of etomidate in comparison to a combination of midazolam and sodium thiopental in reducing the sympathetic response to laryngoscopy and tracheal intubation. Methods: This double-blind, randomized clinical trial study was conducted on two groups of 39 candidates for elective surgery under general anesthesia. Anesthesia was induced by etomidate (E) 0.3 mg/kg in the first group and sodium thiopental 2.5 mg/kg and midazolam 0.075 mg/kg in the second group (TM); then, the patients were intubated. Laryngoscopy findings and cardiovascular response were evaluated during the study. Finally, the data were analyzed using SPSS version 23 (IBM SPSS, Armonk, NY, USA). Results: There was no significant difference between the two groups in terms of age (P = 0.82), weight (P = 0.42), height (P = 0.201), body mass index (P = 0.78), gender (P = 0.65), American Society of Anesthesiologists (ASA) physical status (P = 0.36), and laryngoscopy view grading (P = 0.83). The average laryngoscopy time in the E group was less than the TM group (P = 0.019). In the TM group, at 10 minutes after intubation, mean diastolic blood pressure (P = 0.029) and mean arterial blood pressure (P = 0.023) were significantly lower; however, at other times, there was no significant difference between the two groups (P > 0.05). There was no significant difference between the two groups in terms of adverse responses to laryngoscopy and intubation (P = 0.19). Conclusions: The results of the present study showed that etomidate (E) and a combination of midazolam-sodium thiopental (TM) acted similarly in attenuating the cardiovascular response to laryngoscopy and tracheal intubation, and it seems that TM can be used instead of E if needed.
