Drivers can poorly predict their own driving impairment: a comparison between measurements of subjective and objective driving quality.
Trial report in Psychopharmacology, 2012. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 papers.
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
rationaleAdverse drug effects such as reduced alertness may cause drivers to be unaware that their driving is impaired.
objectiveThis study was conducted to examine if drivers are adequately aware of their driving ability when treated with central nervous system drugs.
methodsData from three clinical trials applying the on-the-road driving test were used to compare the primary outcome measure, the Standard Deviation of Lateral Position, with subjective assessments of alertness before driving, as well as perceived driving quality, and mental effort to perform the test.
resultsThe analyses revealed significant correlations for perceived driving quality (r = -0.498, p < 0.0001), mental effort to perform the test (r = 0.408, p < 0.0001), and alertness taken before driving (r = -0.115, p < 0.017). The predictive validity (R (2)) of perceived driving quality (24.8%), mental effort (16.6%), and alertness before driving (1.3%) was low.
conclusionThe analyses show that subjective assessments do not robustly relate to actual driving performance either in terms of judgments about alertness before the drive or ratings of performance after the drive.
