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: Nutrigenetic research linking fat mass and obesity-associated ( Objectives: The aim of this study is to develop, validate, and apply a cost-effective 4-plex high-resolution melting (HRM) assay for simultaneous detection of Methods: Allele-specific primers with distinct melting temperatures were designed for multiplexed HRM detection of 4 obesity-associated single nucleotide polymorphisms. Analytical validation was performed against Sanger sequencing in 30 samples. Diagnostic accuracy was assessed by sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). The validated assay was applied to genotype 384 Thai adults (123 normal-weight, 261 with overweight/obesity) from Bangkok, Thailand. Genotype frequencies and Hardy-Weinberg equilibrium (HWE) were evaluated by the χ Results: The 4-plex HRM assay demonstrated 100% concordance with Sanger sequencing across all 4 variants (sensitivity: 100%; specificity: 100%; PPV: 100%; NPV: 100%). All triplicate measurements produced consistent genotype calls. Total assay time was 70 min. Based on the manufacturer's catalog prices (QIAGEN, 2024), the estimated reagent cost per sample was ∼4- to 5-fold lower than 4 individual TaqMan assays and 6- to 8-fold lower than Sanger sequencing for the same 4 targets. Population screening revealed minor allele frequencies of 5.3%-8.2% for Conclusions: This validated 4-plex HRM assay provides a rapid, accurate, and cost-effective tool for nutrigenetic screening of obesity-associated variants. The method is suitable for large-scale population studies where budget and infrastructure constraints limit access to high-throughput genotyping platforms.
