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.
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
Insulin resistance is a vital component in the diagnosis of prediabetes. Understanding the factors that influence its development and the course of metabolic disorders should include individual genetic predispositions, which may provide insight into etiology and potential prevention strategies. In this study, we examined associations between MMP-2 -1306 C/T (rs243865) and MMP-9 -1562 C/T (rs3918242) single-nucleotide polymorphisms, serum levels of MMP-2, MMP-9 and TIMP-1, and the occurrence of insulin resistance in patients in a Polish cohort. DNA isolated from 200 unrelated individuals was studied; participants were divided into insulin-resistant and control groups based on the homeostatic model assessment criteria (HOMA-IR). Genotyping of MMP-2 -1306 C/T (rs243865) and MMP-9 -1562 C/T (rs3918242) SNPs was performed using polymerase chain reaction (PCR) and restriction fragment length polymorphism (RFLP) techniques. Serum MMP-2, MMP-9, and TIMP-1 concentrations were measured by enzyme-linked immunosorbent assays (ELISA). No significant associations were observed between the investigated MMP-2 and MMP-9 polymorphisms or TIMP-1 concentrations and the occurrence of insulin resistance. MMP-9 exhibited genotype-related variation, and MMP-2 concentrations differed between the IR and CTR groups. No significant correlations were found between MMP-2 or MMP-9 and TIMP-1. Our data do not support a direct association between the analyzed polymorphisms and insulin resistance in this sample. The observed higher MMP-2 levels in controls warrant further study. Larger, multi-ethnic studies are required to confirm these findings.
