Associations among serum levels of MMP-1, MMP-2, and METAVIR fibrosis score in patients with nonalcoholic fatty liver disease.

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
Aim: We evaluated their diagnostic potential compared to histopathology and standard biochemical tests of liver function. Background: Liver fibrosis is considered a reversible condition, making early diagnosis essential. Serum levels of matrix metalloproteinase (MMP) -1 and MMP-2 are investigated as parameters for diagnosing fibrosis in chronic liver disease. Methods: Commercially available ELISA assays were used to study serum levels of MMP-1 and MMP-2 in 50 patients with nonalcoholic fatty liver disease (NAFLD). Fibrosis stages were evaluated using the METAVIR scoring system. Spearman's coefficient analysed correlations of serum levels of MMP-1, MMP-2, and liver biopsy score, and specificity and sensitivity were calculated through receiver operating characteristic (ROC) analysis. Results: MMP-1 levels in fibrosis stage F1 (14.20±3.10 ng/mL) were not significantly different from stage F2 (9.26±2.21 ng/mL) but were higher (p<0.001) than F3 (7.15±1.56 ng/mL) and F4 (4.53±0.62 ng/mL). MMP-2 levels in F1 (68.57±8.22 ng/mL) were similar to F2 (76.31±9.25 ng/mL) but lower (p<0.001) than F3 (103.34±17.59 ng/mL) and F4 (214.24±46.72 ng/mL). Significant differences were seen between mild fibrosis (F1-2) and severe fibrosis/cirrhosis (F3-4) for MMP-1 (p<0.01) and MMP-2 (p<0.001). Correlation analysis revealed a weak inverse correlation for MMP-1 (r=-0.383, p<0.01) and a weak direct correlation for MMP-2 (r=0.392, p<0.01) with fibrosis stages. MMP-2 levels >86.78 ng/mL had a sensitivity of 73.7% and specificity of 61.3% for fibrosis detection, while MMP-1 levels <4.96 ng/mL had a sensitivity of 52.6% and specificity of 32.3%. Using ROC analysis, MMP-2 had significant diagnostic ability in detecting liver fibrosis stages (area under the curve 0.722, p<0.01). Conclusion: Serum levels of MMP-2 are able to detect liver fibrosis. Despite the limited sample size, these findings support further investigation and potential integration of MMP-2 testing into routine clinical practice.
