The Relationship Between Helmet Weight, Cognitive Performance, and Mental Workload.
Article in Basic and clinical neuroscience. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Introduction: This study sought to examine the effects of helmet weight on cognitive performance and mental workload. Twenty participants were studied in 3 one-hour sessions. Methods: The study participants were requested to read and work with computers under the following 3 conditions: wearing no helmets, wearing a helmet that weighed 800 g (A), and a helmet weighing 1500 g (B). "N-back" task and Continuous Performance Test (CPT) were employed to assess cognitive performance. At the same time, NASA-TLX and Thermal Comfort and Fatigue Perception Scale were used to evaluate mental workload and comfort. At the end of the intervention sessions, perceived mental workload, thermal comfort, and fatigue in the head were measured. Moreover, the research participants' cognitive performance was gauged before and after the sessions. Results: The present study findings revealed that helmet weight significantly impacted cognitive performance (P<0.001). However, no significant difference was detected in the participants' mental workload before and after the intervention. Conclusion: Helmet weight could affect cognitive performance. Therefore, in designing helmets, the helmet's weight should be considered an essential factor. Highlights: Helmet weight significantly impacted cognitive performance.The results showed that the perceived mental workload was not influenced by helmet weight.Designing helmets, the helmet's weight should be considered an essential factor. Plain Language Summary: This study examined the effect of helmet weight on brain performance. The results showed that the perceived mental workload was not influenced by helmet weight. However, brain performance declined as a result of wearing heavier helmets. Furthermore, the perceived local fatigue in the shoulders and neck increased after wearing heavier helmets. Thus, manufacturers should consider helmet weight while designing helmets and developing the relevant standards.
