Comparison of Lidocaine and Dexmedetomidine in Preventing Fentanyl-induced Cough in Patients Undergoing Elective Surgery: A Blinded Randomized Controlled Trial.

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: Fentanyl-induced cough (FIC) refers to a cough that can occur as a side effect of fentanyl, an opioid analgesic primarily used for pain management. Both lidocaine (LIDO) and dexmedetomidine (DEX) are effective in preventing FIC, but the comparative efficacy of each has not yet been thoroughly investigated. Objectives: In this study, we aimed to compare the effect of LIDO versus DEX in preventing FIC in adult patients undergoing elective surgery. Methods: A total of 171 adult patients with American Society of Anesthesiologists (ASA) class I or II undergoing elective surgery were enrolled in this blinded, randomized, placebo-controlled trial. Patients received either 0.5 μg × kg Results: The incidence of cough was 7.0%, 10.5%, and 33.3% in the DEX, LIDO, and saline groups, respectively (P < 0.001). There was no significant difference between the DEX and LIDO groups (P = 0.453), but both were significantly more effective than the control group (P < 0.001 for DEX vs. saline; P = 0.002 for LIDO vs. saline; P < 0.001 for DEX reduced heart rate, systolic and diastolic blood pressure). Conclusions: The results of this study demonstrated that 0.5 μg × kg
