'Cutting Through the Roots': A Critical Appraisal of Transverse and Vertical Sectioning Techniques of Scalp Biopsy for Primary Alopecia.
Article in Indian journal of dermatology. 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
Alopecia, a prevalent and distressing condition with diverse aetiologies, encompasses both scarring and non-scarring types and necessitates accurate diagnostic approaches for effective management. Apart from optimal biopsy site selection based on clinical suspicion, such as active borders for scarring alopecias and lesion borders for non-scarring alopecias, choice of appropriate method for grossing of alopecic scalp biopsies also forms a key step. Historically, debates on 'One (biopsy) Vs Two (biopsies)' and 'Vertical/Longitudinal Vs Horizontal/Transverse' sections persist, each approach carrying its advantages and disadvantages. Traditional methods, such as those proposed by Headington and Whiting, describe the landmarks for slicing a biopsy for transverse section. Newer innovative strategies, including the HoVert technique and the Tyler technique, aim to obtain both vertical and horizontal sections from a single biopsy. This article meticulously presents all the methodologies employed in the grossing of alopecic scalp biopsies in a simplified manner, presents a comprehensive overview of their strengths and limitations, and offers evidence-based recommendation for choosing optimal grossing techniques based on clinical scenarios.
