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

objectiveGamma-ray water monitors (GWMs) are widely used for radioactive wastewater monitoring but can be inaccurate in mixed radionuclide conditions. This study compared radioactivity concentrations measured using a GWM and a high-purity germanium (HPGe) detector and evaluated the validity of derived conversion factors.

methodsWastewater containing

resultsRadioactivity concentrations did not differ significantly between sampling locations or before and after stirring. GWM measurements showed high reproducibility (CV = 1.7%) but consistently produced higher radioactivity concentrations than the HPGe detector. Summed concentration limit ratios were 30.9 and 3.0 for the GWM and the HPGe detectors, respectively, whereas a conversion factor-based estimate was 13.9.

conclusionConversion factors reduced the gap between GWM and HPGe detection and provided estimates closer to HPGe-based values, facilitating more efficient discharge management in targeted radionuclide therapy facilities.
