In Vivo Reflectance Microscopy of Meissner Corpuscles and Bedside Measures of Large Fiber Sensory Function: A Normative Data Cohort.

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 AND
objectivesThe goal of this work was to establish age-, sex-, and body dimension-adjusted normal cutoff values for Meissner corpuscle (MC) densities via in vivo reflectance confocal microscopy (RCM), timed vibration sensory thresholds with a 128-Hz tuning fork, and touch-pressure sensory thresholds with standardized monofilaments for clinical and research application.
methodsSeventy-seven prospectively recruited individuals without signs or symptoms of peripheral neuropathy or a condition or neurotoxin exposure that can alter sensory function underwent cross-sectional evaluation of MC densities via in vivo RCM, monofilament touch-pressure sensory thresholds, and timed vibration sensory thresholds in nondominant upper and lower extremities. Age-, sex-, and body dimension (e.g., height)-adjusted normal values were developed. The fifth percentile for MC densities and timed vibration thresholds and 95th percentile for MF touch-pressure thresholds were selected as normal cutoff points.
resultsParticipants were 9 to 89 years of age. Age and sex were uniformly distributed. Timed vibration and touch-pressure thresholds were less sensitive with increasing age and were more sensitive in the hand than in the leg or foot within individuals. Timed vibration thresholds did not differ by sex or body dimensions. Touch-pressure thresholds were lower (more sensitive) at the thenar eminence and digit V in the hand in women compared to men but otherwise did not differ by sex at other measurement locations. Body dimensions did not affect touch-pressure thresholds. There were no apparent age-related floor effects for the 5th and 95th percentile normal cutoff values for timed vibration or touch-pressure thresholds, respectively. MC densities also declined with age and were highest at digit V and lowest at the arch within individuals. MC densities were affected by sex or body dimensions at all imaging sites, with lower densities seen in male participants or larger individuals. MC densities were quantifiable in the hand of all participants and were associated with touch-pressure thresholds at all locations. DISCUSSION: This study establishes age-, sex-, and body dimension-adjusted normal cutoff values for 2 easily applied measures of large fiber sensory function and RCM assessment of MC densities for multiple limb locations. These results will aid in the detection and monitoring of peripheral sensory nerve disorders.
