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

People all over the world, independent of their culture or background, touch their faces up to 800 times per day. No other part of the body is touched as often as the face. Forehead, nose, and chin-the so-called T-zone of the face-are touched particularly frequently during spontaneous facial self-touches (sFST). It is hypothesized that there is a relationship between the density of mechanoreceptors (inferred from facial hair distribution) and the frequency of spontaneous self-touching. In order to indirectly measure the density of mechanoreceptors (cutaneous end organ complexes), the number of vellus and terminal hairs at 40 different measuring points on the face of 30 (15f/15m) healthy volunteers in study A is determined. In study B, the frequency of sFST at the same 40 measuring points in 66 (32f/34m) healthy persons is determined. Study A reveals that the number of facial hairs-in both sexes-is higher in the T-zone than in other areas of the face. Study B reveals that the T-zone is touched more frequently than other areas of the face. Skin areas of the face with a higher number of vellus hairs (and presumably higher innervation density) are touched particularly frequently during sFST.
