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: Needlestick and sharp injuries (NSIs) are a significant occupational hazard for dental practitioners, carrying a substantial risk of bloodborne pathogen transmission. This study aimed to determine the prevalence, characteristics, and factors associated with NSI exposures among dental practitioners in Sana'a, Yemen. Materials and methods: An online survey was conducted among dental practitioners at university dental hospitals, public health centers, and private clinics in Sana'a, Yemen. The self-administered questionnaire collected information on demographic background, history of NSIs, post-exposure practices, infection control compliance, and perceptions. Multivariable logistic regression was used to identify factors independently associated with lifetime NSI. Results: The lifetime prevalence of NSI was 88.18% (373/423). Among those with NSI, 36.19% reported one injury in the past 12 months, and 24.66% reported four or more injuries. The most common device was the syringe needle (61.66%), and the most frequent procedure was local anesthesia administration (39.14%). Only 11.26% of injured participants underwent post-exposure testing for bloodborne viruses, and only 9.38% received post-exposure prophylaxis. In multivariable analysis, treating more than 12 patients per day was independently associated with increased odds of NSI (adjusted odds ratio 3.50; 95% CI 1.45-8.46; Conclusion: The extremely high prevalence of NSI among dental practitioners in Sana'a, Yemen, together with very low uptake of post-exposure measures, represents a critical occupational safety failure. High patient volume emerged as a potentially modifiable associated factor. Interventions should be evaluated to prioritize workload management, universal access to safety-engineered devices, and systematic post-exposure protocols, alongside educational efforts to counter the perception that NSIs are inevitable.
