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

aims/hypothesisGenetic association studies have demonstrated that partial loss of SLC30A8 Function protects against type 2 diabetes in humans. We investigated the impact of complete loss of SLC30A8 Function on type 2 diabetes risk and related phenotypes in humans.

methodsThe Pakistan Genome Resource (PGR), a biobank comprising whole-exome and whole-genome sequences of 145,037 participants, was analysed for phenotypic associations with SLC30A8 loss-of-function (LoF) variants. To follow up on the observations in the PGR, we conducted recall-by-genotype analyses of SLC30A8 LoF heterozygotes and homozygotes, as well as their participating family members, using OGTTs.

resultsWe identified 18 SLC30A8 knockouts, including homozygotes for a variant enriched in South Asians (Gln174Ter), and 1024 heterozygotes for LoF variants. Type 2 diabetes risk was lower in SLC30A8 LoF heterozygotes and homozygotes relative to non-carriers, and the protective effect strengthens in a gene dose-dependent manner (OR CONCLUSIONS/

interpretationThe corrected insulin response, disposition index and insulin sensitivity index in LoF heterozygotes and homozygotes indicated higher glucose-stimulated insulin secretion with preserved beta cell function that was independent of BMI. These data suggest that therapeutic inhibition of SLC30A8, up to and including complete knockout, may treat type 2 diabetes safely and effectively.
