Diagnostic performance of narrow-band imaging bronchoscopy in assessing tracheobronchial cell morphological abnormalities.
Article in Annals of thoracic medicine. 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
backgroundNarrow-band imaging (NBI) bronchoscopy increases the diagnostic accuracy of lung cancer by enhancing mucosal surface structure images. The accuracy of NBI bronchoscopy for morphological abnormalities of tracheobronchial cells is unknown. This study aims to determine the diagnostic performance of NBI bronchoscopy in assessing tracheobronchial cell morphological abnormalities in nontumor mucosal airways.
methodsThis diagnostic study was conducted at Persahabatan Hospital from March 2023 to January 2024 using consecutive sampling. Participants aged over 18 with central lesions underwent NBI bronchoscopy. NBI vascular patterns were evaluated as the index test, with the gold standard being tracheobronchial cell morphological abnormalities assessed through histopathological examination. Diagnostic metrics, including sensitivity, specificity, and area under the curve (AUC), were analyzed using IBM SPSS Statistics 26.0.
resultsAmong the 99 analyzed subjects, 46 exhibited abnormal vascular patterns on NBI bronchoscopy. A tortuous pattern exhibited the highest sensitivity and specificity (42.8% and 91.5%, respectively), compared with dotted and abrupt-ending patterns. Specificity for dotted and abrupt-ending patterns was 90.1% and 85.9%, respectively. However, as a potential screening modality, each NBI vascular pattern demonstrated low sensitivity, ranging from 14.3% to 42.8%. Combining tortuous, abrupt-ending, and dotted patterns improved diagnostic performance, achieving an AUC of 71.0%, sensitivity of 75.0%, and specificity of 67.6%.
conclusionNBI bronchoscopic vascular patterns are correlated with tracheobronchial cellular morphological abnormalities, demonstrating high specificity and moderate sensitivity.
