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

Background Hair loss significantly affects physical appearance and psychological well-being, leading to increased use of hair growth and hair loss prevention treatments. Accurate and reproducible assessment of scalp and head crown surface area and hair count is essential for evaluation in clinical and cosmetic clinical studies with hair care products. Objective and method This prospective, single-visit standardization and validation study included adult participants aged 18 to 55 years. Scalp surface area measurements were performed in 25 adult participants using a calibrated measuring tape. Head crown (vertex) surface area measurements, including the frontal and mid-scalp regions, were performed in 25 adult participants using a calibrated measuring tape and photographic image analysis with Image-Pro software. For hair count assessment, global 90° head photographs obtained from in-house data of 50 participants were analyzed using phototrichogram (PTG)-based CASLite NOVA and Image-Pro software. Agreement between the measurement methods was evaluated using appropriate method-comparison statistical analyses. Result The scalp surface area mean was 492.36 ± 30.97 cm².
