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

Ruthenium isotopes produced by fission in nuclear materials could be valuable signatures for nuclear verification or non-proliferation monitoring. In this study, ruthenium (Ru), uranium (U), and plutonium (Pu) isotope ratios and concentrations were measured in six different samples taken along a single nuclear fuel rod from a pressurized water reactor (PWR). The Ru isotope ratios [Formula: see text]Ru/[Formula: see text]Ru, [Formula: see text]Ru/[Formula: see text] and [Formula: see text]Ru/[Formula: see text]Ru increase upon moving from the end of the rod towards the center, correlating with the amount of burnup of the fuel indicated by U and Pu isotope ratios. Ruthenium fission product concentrations also increase near the center of the rod, consistent with other isotopic and elemental concentration data indicative of burnup. The measured Ru ratios clearly comprise inputs from both fission and neutron capture reactions. These measurements serve as important experimental validation of previous theoretical studies suggesting that Ru isotope ratios reflect the burnup of nuclear fuel and could be used to distinguish between reactor types.
