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

Anthropogenic and natural sources of volatile organic compounds (VOCs) have been associated with hematological, cardiovascular, and respiratory diseases. VOCs can also track directly from the nose to the olfactory bulb (OB). This study investigated whether inhaled VOC-induced toxicity increases free radical generation and oxidative stress biomarker levels along the olfactory neural pathway from the nasal mucosa to brain regions implicated in Alzheimer's disease. In this study, twenty male six-week-old Landrace piglets were randomly divided into three groups and daily exposed to VOCs for eight weeks: Group A (unexposed piglets; n = 6), Group B (2 h exposure; n = 7), and Group C (3 h exposure; n = 7). The VOC mixture consisted of 5% formaldehyde, 5% benzene, 10% toluene, 10% xylene, and 70% water, and released at a steady-state Total VOC (TVOC) level of 1.0 mg/m3 range (0.6 - 1.8 mg/m3) in the test room. Biomarkers of oxidative stress, antioxidant status, and pro-inflammatory cytokines were assessed in the nasal mucosa, olfactory bulb, pyriform cortex, entorhinal cortex, and hippocampus. Exposure of piglets to VOCs significantly elevated malondialdehyde, hydrogen peroxide (H
