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

backgroundMercury (Hg) is a naturally occurring heavy metal with high toxicitythat affects various organs. This study aimed to evaluate the protective effects of N-acetylcysteine (NAC) on the lung tissue of Wistar rats exposed to mercury.

methodsRats were divided into five groups: H1 (control), H2 (single dose of Hg), H3 (continuous dose of Hg), H4 (single dose of Hg+ single dose of NAC), and H5 (continuous dose of Hg+ continuous dose of NAC). The expression levels of SOD1, NOS, TIMP1, Fibronectin1, HIF1, MPO, MMP2 and TIMP2 were analyzed using qRT-PCR.

resultsMercury levels in the blood and lung tissues significantly increased in the H2 and H3 groups compared to the H4 and H5 groups, respectively. Hg exposure in H3 group significantly (P < 0.001) led to the upregulation of MPO (4.55-fold), HIF1(4.31-fold), MMP2 (4.20-fold), TIMP1(3.18-fold), TIMP2 (4.83-fold), NOS (3.52-fold), and FN1 (3.52-fold), along with the downregulation of SOD1 (0.51-fold) compare to control group (H1). In contrast, rats treated with NAC after Hg exposure in H5 group significantly (p < 0.01–0.001) showed downregulation of MPO (2.49-fold), HIF1(2.12-fold), MMP2 (1.94-fold), TIMP1(1.92-fold), TIMP2 (1.96-fold), NOS (2.00-fold), and FN1 (1.90-fold), and upregulation of SOD1 (0.76-fold) compare to H3 group. A significant reduction in mercury levels was also observed in the blood and lung tissue of rats treated with NAC compared to those exposed Hg alone.

conclusionNAC exerts a protective effect against mercury-induced cytotoxicity and genotoxicity in rat lungs by scavenging mercury and modulating the expression of oxidative stress-related genes.
