Complications during interventional rigid bronchoscopy with general anaesthesia and high-frequency jet ventilation: a 5-year retrospective pilot study.
Article in European journal of anaesthesiology and intensive care, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map.

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.

Abstract
backgroundHigh-frequency jet ventilation (HFJV) is the standard technique for rigid bronchoscopy. Few studies have comprehensively examined the complications associated with this technique. Previous evidence suggests that an ASA 4 score and basal SpO
objectivesThis retrospective study aimed to quantify and characterise the frequency and types of complications linked to HFJV, and to identify independent factors associated with their occurrence.DESIGN A retrospective pilot cohort study.
settingThis monocentric pilot study was conducted in a tertiary university hospital in Brussels, Belgium, between 1 January 2019, and 31 December 2023. PATIENTS: A total of 1385 patients who underwent bronchoscopy under general anaesthesia were screened, of whom 833 (444 men and 389 women) met inclusion criteria and were retained for final analysis. Inclusion criteria were age at least 18 years, rigid bronchoscopy and general anaesthesia using HFJV. Exclusion criteria included endotracheal intubation, incomplete medical records or explicit refusal to allow the use of their medical records for research.
main outcome measuresComplications were defined as hypoxaemia (oxygen saturation ≤ 90% for at least 1 min), hypotension (SBP < 90 mmHg), cardiac arrhythmia, laryngospasm or bronchospasm, pneumothorax or requirement for ICU admission. Univariate analyses were performed to compare groups of patients with and without complications, and variables with
resultsHypoxaemia and hypotension were the most frequent periprocedural events occurring in 11 and 28% of cases, respectively. Shorter stature, stent implantation and basal oxygen saturation below 96% emerged as independent predictors of incidents during HFJV for rigid bronchoscopy (logistic regression model, area under the curve 0.62 (95% CI 0.58 to 0.67).
conclusionsWe observed a relatively high number of minor complications associated with general anaesthesia for interventional bronchoscopy using HFJV. Shorter stature, lower basal SpO
