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.
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
Land can be put into different uses with little consideration of attendant effects on human health and environment. This study aimed to assess the levels of natural radioactivity (40K, 226Ra and 232Th) and associated radiological hazards in soil samples from selected land use types in parts of Abeokuta metropolis, southwest Nigeria. A total of thirty (30) composite surface (0–30 cm) soil samples from six (6) different land uses—abattoir waste site (ABT), cement block making site (BMS), textile dye-contaminated site (DCS), automobile mechanic village site (MVS), welding & fabrication site (W&FS) and grassland (GLS) were collected and determined for activity concentration (AC) of natural radionuclides using NaI (Tl) scintillation detector. Radiological hazard indices (RHI) were later calculated using established UNSCEAR relations. The results of soil natural radioactivity levels revealed that the average ACs of 226Ra (57.66 ± 33.48–156.67 ± 48.78 Bq/kg) and 232Th (131.68 ± 41.10–213.96 ± 45.00 Bq/kg) in all investigated land uses were higher than their corresponding global mean values of 39 and 45 Bq/kg, correspondingly. The soils from all selected land uses had average AC of 40K (206.34 ± 69.98–316.68 ± 67.54 Bq/kg) below the weighted world average value of 420 Bq/kg. Average values of RHI such as annual dose rate (118.90–196.39 nGyhr−1), outdoor annual effective dose equivalent (145.82–240.86 μSv/yr), annual gonadal dose equivalent (821.28–1350.53 μSv/yr), gamma level index (1.89–3.09) and activity utilization index (2.21–3.69) of soils in all selected land uses were above the global average standards. Excess lifetime cancer risk values ranged from 0.51 to 0.84 × 10−3, exceeding the global average of 0.29 × 10−3. Multivariate statistics revealed that 232Th is the primary contributor to the radiological hazard. This study revealed considerable radiological risks from natural radionuclides in the topsoils of investigated land use types.
