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 total of sixty surface sediment samples were systematically obtained from ten distinct locations along the Sudanese coastline of the Red Sea during the summer season (June 2016) and the winter season (February 2017), subsequently analyzed using high-purity germanium (HPGe) gamma spectrometry. The activity concentrations of natural radionuclides (40K, 226Ra, 232Th) as well as the anthropogenic radionuclide (137Cs) were quantified. During the summer, the concentrations recorded were as follows: 40K = 219 ± 169 Bq/kg, 226Ra = 6.94 ± 3.59 Bq/kg, 232Th = 6.32 ± 3.13 Bq/kg, and 137Cs = 1.89 ± 1.15 Bq/kg. The relatively large standard deviation, particularly for 40K, reflects spatial variability among the different sampling locations. The values recorded during the winter season exhibited a slight reduction. The highest activity levels were detected at Port Sudan Harbor, likely attributed to the influence of industrial activities and the composition of sediments. Correlations among the radionuclides suggest analogous geochemical behaviors. The radiological hazard indices, including Raeq and AEDE, were found to be substantially lower than global safety levels. No indications of recent anthropogenic inputs of 137Cs were identified, supporting prior findings within the region. This study contributes updated baseline data and facilitates a comparative analysis with previous research conducted in both Sudanese and neighboring Red Sea locales.
