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

Heavy metals intoxication is known to be risk factors for various diseases, including cancer. These metals may be presented in food and soil as well as in leaf and tobacco smoke. The aim of this study was to correlate the exposure to heavy metals stemming from tobacco and head and neck squamous cell carcinoma carcinogenesis. Analysis of lead, copper, manganese, arsenic, chromium, and cadmium by atomic absorption spectrophotometry was performed in whole blood samples from 91 patients: 68 smokers with oral cavity, pharynx, or laryngeal cancer; 8 non-smokers with oral or larynx cancer; and 15 non-cancer smokers with tobacco-related diseases (control group). No differences were found in metals quantifications, except a significant difference was observed (p = 0.0223) with higher mean in copper levels for non-smokers with cancer. The present study concluded, for the groups evaluated, it was not possible to prove the relationship between the studied metals in the development of the neoplasm. On the other hand, the results of copper demonstrated a correlation with smokers with cancer and lower levels of circulating copper.
