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

A study of trace elements pollution in the cobalt-nickel mining area of Nkamouna-Kongo (East Region of Cameroon) and their intimation to the risk of human exposure was carried out. A large spatial variability of concentrations was observed in the geochemical analysis of the trace elements in the thirty samples investigated. Trace element pollution in the investigated samples was assessed using the Regional Screening Level calculator of Environmental Protection Agency (USEPA) and the collected sample were analyzed using a SPECTRO XEPOS Energy Dispersive X-Ray Fluorescence analyzer (ED-XRF). The trace element concentrations in the analyzed samples followed the following order: Fe > Cr > Mn > Zr > Ni > Ba > Rb > Cu > Zn > Sr > Ga > Pb > Co > Rb > As > Sn. The averages of trace elements contamination factors followed a decreasing order:: Cr > Ni > Fe > As > Co > Cu > Zr > Ga > Pb > Mn > Zn > Y > Rb > Ba > Sn > Sr. Enrichment factor studies revealed that chromium (Cr) was severely enriched (indicating that Cr is the main element of the anthropic load) while elements such as Ni, Ba, Mn, Co, Cu, Zn, Ga, As, and Pb were moderately enriched. The associated health risk of human exposure was investigated using the Regional Screening Level of Environmental Protection Agency. It was found out that the carcinogenic risk to the exposed population from ingestion is high (2.5E-03), while the dermal risk is moderate (7.08E-04) and the inhalation risk is low (2.50E-07). The total non-carcinogenic risk from trace elements exposure for adults (HI = 1.5) and children (HI = 1.47E + 01) indicates that non-carcinogenic effects may occur in the vicinity of the study area.
