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: The human skin microbiota is shaped by host-specific factors such as age, diet, geography and environment. However, the interplay between these, especially host genetics and skin microbiota composition remains largely unexplored in Indians. Monozygotic twins share 100% of their genetic makeup, thereby providing a unique opportunity to investigate the associations between genetic relatedness, environmental variation, and microbiota composition. Methods: We collected axillary sweat samples from thirteen monozygotic twin pairs ( Result: In the present study Conclusion: This pilot study expands the current knowledge of the skin microbiota and its association with genetic relatedness and other potential confounders. We demonstrated the association of twins' skin microbiota composition and diversity with geographical location; however, further studies with a larger representation of monozygotic (MZ), dizygotic (DZ) and sibling-parent pairs living in different households are needed to understand the interplay between genetics, environmental variation, and skin microbiota diversity, and composition.
