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

Tandem repeats (TRs) are highly variable loci in the human genome that are linked to various human phenotypes. Accurate and reliable genotyping of TRs is important in understanding population TR variation dynamics and their effects in TR-trait association studies. In this protocol, we describe how to generate high-quality consensus TR genotypes for population genomics studies. In particular, we detail steps to: (i) perform TR genotyping from short-read whole-genome sequencing data by using the HipSTR, GangSTR, adVNTR and ExpansionHunter tools, (ii) perform quality control checks on TR genotypes by using TRTools and (iii) integrate TR genotypes from different tools by using EnsembleTR. We further discuss how to visualize and investigate TR variation patterns to identify population-specific expansions and perform TR-trait association analyses. We demonstrate the utility of these steps by analyzing a small dataset from the 1000 Genomes Project. In addition, we recapitulate a previously identified association between TR length and gene expression in the African population and provide a generalized discussion on TR analysis and its relevance to identifying complex traits. The expected time for installing the necessary software for each section is ~10 min. The expected run time on the user's desired dataset can vary from hours to days depending on factors such as the size of the data, input parameters and the capacity of the computing infrastructure.
