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

backgroundFTO is a gene located in chromosome region 16q12.2. Recently two studies have found associations of several single nucleotide polymorphisms (SNPs) in FTO with body mass index (BMI) and obesity, particularly rs1421085, rs17817449, and rs9939609.

methodsWe examined these three SNPs in 583 extremely obese women with current BMI greater than 35 kg/m2 and lifetime BMI greater than 40 kg/m2, and 544 controls who were currently normal weight (BMI<25 kg/m2) and had never been overweight during their lifetimes.

resultsWe detected highly significant associations of obesity with alleles in all three SNPs (p < 10-9). The strongest association was with rs1421085 (p = 3.04 x 10-10, OR = 1.75, CI = 1.47-2.08). A subset of 99 cases had extremely discordant sisters with BMI<25 kg/m2. The discordant sisters differed in allele and genotype frequencies in parallel with the overall case and control sample. The strongest association was with rs17817449 (z = 3.57, p = 3.6 x 10-4).

conclusionThese results suggest common variability in FTO is associated with increased obesity risk or resistance and may in part account for differences between closely related individuals.
