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

Trichophyton indotineae, first identified in India, has increasingly been reported in Asia, the Middle East, Europe, and recently in the USA. The global spread of terbinafine-resistant T. indotineae underscores the urgency of the issue. With its ability for human-to-human transmission, it can be considered anthropophilic. However, its highly virulent nature suggests a possible link to zoophilic species, raising the potential for disease transmission from animals. In this study, we have performed whole genome sequencing (WGS) of terbinafine susceptible and resistant Trichophyton species from animal and human origin to understand transmission dynamics of this species. Thirteen isolates of Trichophyton spp. from human (n = 9) and canine (n = 4) origin, respectively from Chandigarh and Bareilly, India, were included in this study. Isolate identification based on ITS extracted from WGS data identified six T. indotineae (ITS genotype VIII) and seven T. interdigitale (ITS genotype II) isolates. WGS single nucleotide polymorhpism (SNP) analysis separated the isolates into two distinct groups, T. indotineae and T. interdigitale and showed the clonal nature of both species. For both species, low SNP differences between isolates from humans and dogs were observed as well as low differences between isolates from Chandigarh and Bareilly, cities >350 km apart from each other. These findings suggest zoonotic transmission, next to fast spread across large distances. The T. indotineae terbinafine-resistant strains exhibited the SQLE
