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

backgroundThis study focused on the differences in hairy root fungal microecology between androgenetic alopecia patients and healthy individuals.

methodsLight microscopy was used to observe the morphology of hairy roots. Morphological observations were also performed in the positive specimens using scanning electron microscopy and transmission electron microscopy. The high-throughput sequencing method was used to detect the fungal microecology of hairy roots at different sites. Moreover, the comparison of fungal loads of Malassezia in different group and scalp area were tested by PCR.

resultsThe fungi in the hair root observed by optical microscopy are mainly Malassezia yeast. The positive rate of Malassezia in the hair loss group (60%) was higher than that in the control group (40%). The detection efficiency of Malassezia examined by scanning electron microscopy was higher than that by light microscopy. Results acquired from high-throughput molecular sequencing of fungi suggested that Ascomycota was the dominant species, whereas in the occipital hair roots of the control group Basidiomycota was the dominant species in the hair loss group. Malassezia followed by Trichosporon were the most abundant fungal genera. The changes in abundance at the top and occipital region of the control group were more significant than those of the genus Fusarium, followed by Epicoccum and Malassezia. The load of Malassezia located on calvaria in the alopecia group was significantly higher than that in the control group. In the alopecia group, the load of Malassezia on the scalp was higher than that on the occipital region. The load of Malassezia globosa and Malassezia restricta in the hair loss group was higher on calvaria and occipital areas.

conclusionMalassezia had a positive correlation with the incidence of androgenic alopecia.
