Combining four screening tools for cost effective screening of OSA in train drivers: A UK experience.

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: Obstructive sleep apnoea (OSA) in drivers/workers has been implicated in railway and road traffic safety incidents; however, there are insufficient data on its prevalence and cost-effective screening methods. Aim: This pragmatic study examines four OSA screening tools: the Epworth sleepiness scale (ESS), the STOP-Bang (SB), the adjusted neck circumference (ANC) and the body mass index (BMI), exploring their suitability and effectiveness separately and in combination. Method: Using all four tools, 292 train drivers were opportunistically screened between 2016 and 2017. A polygraph (PG) test was carried out when OSA was suspected. Patients with an apnoea-hypopnea index (AHI) ≥5 were referred to a clinical specialist and reviewed annually. Those who had continuous positive airway pressure (CPAP) treatment were evaluated for compliance and control. Results: Of the 40 patients who had PG testing, 3 and 23 participants met the ESS >10 and SB >4, criteria, respectively, whereas 25 participants each had an ANC >48 and a BMI >35 with a risk factor or ≥40 with none. OSA was detected in 3, 18 and 16 of them who met the ESS, SB and ANC criteria, respectively, and was positive for OSA in addition to 16 others who met the BMI criteria. A total of 28 (72%) were diagnosed with OSA. Conclusion: Although when used individually, these screening methods are less effective/inadequate, combining them is easy, feasible and offers the maximum chance of OSA detection in train drivers.
