Diagnostic yield of bronchoscopy in hemoptysis without radiological abnormalities: A retrospective cohort study.
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
backgroundBronchoscopy is widely used to evaluate the source and cause of hemoptysis. Its diagnostic value is well established in patients with abnormal radiological findings; however, its utility in patients without such findings remains uncertain.
methodsWe retrospectively included adults with hemoptysis who underwent bronchoscopy between January 2019 and June 2023 and were followed up clinically and radiologically for at least 1 year. Computed tomography (CT) scans were reviewed and categorized as pathological or nonpathological; cases with pathological findings were further classified according to malignancy suspicion. The diagnostic yield of bronchoscopy was compared between groups. Receiver operating characteristic (ROC) analysis was used to derive an age cutoff; multivariable logistic regression identified independent predictors.
resultsA total of 380 patients were included (mean age 58.3 ± 14.6 years; 78.9% males). Bronchoscopy was diagnostic in 37.6% of cases. Diagnostic yield was significantly higher in patients over 50 years of age, in males, and in those with abnormal CT findings. In contrast, bronchoscopy was rarely diagnostic in patients younger than 50 years with normal CT. Logistic regression showed a 3.5-fold increase in diagnostic yield with age (odds ratio [OR]: 3.48, 95% confidence interval [CI] 1.27-9.53,
conclusionBronchoscopy provides meaningful diagnostic information in patients aged ≥50 years and/or with CT findings suspicious for malignancy, whereas its yield is limited in younger patients with normal CT. A selective approach may be appropriate in low-risk cases.
