1 · What the graph read from 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.

2 · The registry

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: Fiberoptic bronchoscopy (FB) under sedation can provoke patient discomfort, cough, and hemodynamic fluctuations. This study evaluated the efficacy and safety of dexmedetomidine nasal spray as a premedication compared to intranasal normal saline and lidocaine. Methods: A total of 90 patients scheduled for FB under sedation were randomly assigned to three groups. Group D (dexmedetomidine), Group C (control, normal saline), and Group L (lidocaine) received pre-induction nasal sprays via the same metered-dose aerosolization device. At 10 min post-spray, all patients received standard monitored anesthesia care (MAC) with preserved spontaneous ventilation (respiratory rate, RR ≥10 breaths/min; peripheral oxygen saturation, SpO Results: Group D demonstrated better overall performance. Hemodynamically, HR in Group D was lower than Group C at T Conclusion: Premedication with dexmedetomidine nasal spray in patients undergoing FB under sedation was associated with more effective suppression of procedure-induced cough, better hemodynamic stability, a lower incidence of PONV, and a faster recovery profile compared to both intranasal saline and lidocaine, without increasing respiratory depression. Consequently, dexmedetomidine nasal spray can effectively and safely enhance patient comfort and safety, and optimize the procedural conditions for the bronchoscopists.
