Follicular Map: A Novel Approach to Quantitative Trichoscopy.
Article in Skin appendage disorders, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundTrichoscopy (hair and scalp dermoscopy) is gaining importance as an easy-to-use diagnostic and monitoring tool in various hair and scalp conditions.
objectiveThe demand for a method to identify exactly the same site on scalp skin for subsequent examinations is growing constantly.
methodsIn total, 40,000 trichoscopic images of 70-fold magnification were analyzed. Graphical pattern recognition was used to identify hair shafts in trichoscopy images and to derive the coordinates of all follicular orifices. Determination of the relative positions of hair follicle orifices formed the Follicular Map (FMap). Processing and matching of FMaps involves conceptually simple but computationally complex numerical algorithms.
resultsFMaps were shown to be unique for specific locations on the scalp in each human individual. The follicular patterns were not affected by natural hair cycling processes and remained unchanged over the course of time. It has been tentatively verified that FMaps remain unaffected by noncicatricial alopecia.
conclusionsThe concept of FMap presents a novel approach to qualitative trichoscopy, allowing precise evaluation of treatment efficiency, clinical trial quality control, validation of diagnostic tools, and potentially other applications still to be discovered. The FMap enables the location of hair follicles to be precisely measured and recorded.
