Comparison Between Video Laryngoscope and Direct Laryngoscope for Pressor Response in Adult Patients Undergoing Craniotomy.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectivesThis prospective randomized study was done to compare hemodynamic and intraocular pressure (IOP) responses to laryngoscopy and intubation with the use of the Macintosh direct laryngoscope (DL) (Medisearch Systems Pvt. Ltd., Jalandhar, India) and C-MAC video laryngoscope (VL) (C-MAC®, Karl Storz, Tuttlingen, Germany) in patients undergoing brain tumor excision surgery. MATERIALS AND
methodsSixty American Society of Anesthesiologists (ASA) grade I and II patients aged 18-65 years undergoing fronto-parietal brain tumor excision surgery were randomly allocated into two groups: group DL (intubation using Mcintosh DL) (n=30) and group VL (intubation with C-MAC® VL) (n=30). Baseline values of mean arterial pressure (MAP), systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), and IOP were recorded. The primary outcome was the percentage change in MAP. Secondary outcomes were percentage changes in HR, SBP, DBP, and IOP. Hemodynamic parameters were noted during laryngoscopy (T STATISTICAL ANALYSIS: Categorical variables were presented in numbers and percentages, and continuous variables were presented as mean±SD and median. Normality of data was tested by the Kolmogorov-Smirnov test. The unpaired t-test/Mann-Whitney U test was used for comparing quantitative variables, and the chi-squared test/Fisher's exact test was used for qualitative variables. A p-value lower than 0.05 was considered statistically significant.
resultsThe percentage rise in MAP was significantly greater in the DL group as compared with the VL group at all time points during laryngoscopy: T
conclusionsIn elective neurosurgical patients, the C-MAC VL resulted in a lower rise in hemodynamic parameters and IOP as compared to DL.
