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

purposeIntact tactile perception is essential to successfully interact with objects. While tactile examinations exist for capturing tactile impairments, recent investigations underscore that these examinations remain insufficient, particularly for adults following a neurological injury. To inform the design of improved tactile assessments, this study comprehensively captures factors that can influence tactile perception in young and older adults who are neurologically intact.

methodsWe examined the impact of arm dominance (dominant/non-dominant), nerve (median/ulnar/radial), location (hand/elbow), and sex (male/female) on thresholds at which electrotactile stimuli could be consciously detected when applied to the skin in 20 young and 14 older right-arm dominant participants.

resultsSignificant differences depending on arm dominance were not found in young (p = 0.6781) or older (p = 0.2786) adults. Yet, the nerve tested did yield differing thresholds in young (p < 0.0001) and older (p < 0.0001) adults. In young adults, thresholds were less at the hand than elbow (p = 0.0031). In older adults, the average threshold was greater at the hand than elbow. Importantly, in older adults the threshold at the hand increased with age to a greater extent than at the elbow (p < 0.0001). Thresholds were greater in males than females in young adults (p = 0.0004), whereas no significant sex differences were observed in older adults (p = 0.2560).

conclusionThis work highlights the importance of addressing numerous factors and their interactions when assessing tactile perception (e.g., arm dominance, nerve, location, sex, age). Findings can inform the design of improved tactile assessments that more accurately capture why impairments arise, including following a neurological injury.
