Comparison of Nebulized Lidocaine and Intratracheally Injected (Spray-as-you-go) Lidocaine in Pain and Cough Reduction during Bronchoscopy.
Article in Tanaffos, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers, 1 of them a synthesis that pooled 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.
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: Patients undergoing bronchoscopy often suffer from pain, coughing, and suffocation. Therefore, lidocaine is prescribed through various methods to induce local anesthesia. This study aimed to compare nebulized lidocaine and intratracheally injected lidocaine in pain and cough reduction during bronchoscopy. Materials and Methods: This clinical trial was performed on 96 patients, divided into two groups of intervention (receiving lidocaine via a nebulizer before bronchoscopy) and control (receiving lidocaine through the working channel of bronchoscope). Then, the patients᾽ cough frequency was recorded during the procedure, and the pain level was measured using a numerical rating scale at the end of the procedure. The data were analyzed with SPSS software (version 16) using the chi-square and Fisher's exact tests. Moreover, the linear and Poisson regression tests were applied to analyze the main variables in this study. Results: There was no significant difference between the two groups regarding demographic characteristics (P>0.05). Moreover, the linear regression test revealed that the intervention (nebulized lidocaine) group had significantly lower pain scores (1.54±0.08) than the control (intratracheally injected lidocaine) group (2.5±0.26) (P=0.013). In addition, the Poisson regression test showed a statistically significant difference between the intervention (35.22±2.93) and control (48.85±5.96) groups in terms of cough frequency (P<0.0001). Conclusion: This study indicated that nebulized lidocaine has higher efficacy in reducing the patients᾽ pain and cough during bronchoscopy than intratracheally injected lidocaine.
