Aspirin use is safe in patients undergoing transbronchial lung cryobiopsy.
Article in Heliyon, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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: Aspirin has been shown to be safe for patients undergoing certain diagnostic bronchoscopy procedures, such as transbronchial biopsies and endobronchial ultrasound (EBUS)-guided transbronchial needle aspiration. However, there are no studies documenting the safety of aspirin in patients undergoing Objective: To determine whether aspirin increases the risk of bleeding during or following TBLC. Methods: 172 consecutive patients undergoing TBLC were included in this retrospective cohort study. Data on demographic characteristics, comorbidities etc. were collected. Bleeding severity was defined by the intervention needed to stop the bleeding: mild-cold saline injection, moderate-adrenalin/hexakarpon injection, or severe - Intensive Care Unit admission after bronchoscopy. Results: Fifty-one patients (29.6 %) were under aspirin treatment at the time of TBLC. Overall, there was no significant difference between the aspirin and the control groups regarding the incidence of moderate-severe bleeding (41.2 % vs. 33.1 %, respectively, p.0.31). the Clopidogrel was found as a risk factor for increased bleeding when taken together with aspirin (Odds ratio = 9.8 (1.1-86), p = 0.013). When taken alone, clopidogrel was also found as a risk factor to increased bleeding, yet these results didn't reach significance due to low number of patients (fig. 1, N = 5, Odds ratio = 2.8 (0.46-17.35), p = 0.245). No difference was observed between the groups regarding additional post-procedural complications, including pneumothorax, hospitalizations, and mortality. Conclusion: To the best of our knowledge, this is the first study examining bleeding risk of cryobiopsy under aspirin treatment. Based on our results, it seems safe to perform TBLC under aspirin treatment, except for patients who are concurrently treated with clopidogrel. Further research should be conducted to substantiate this conclusion.
