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

Rivers are major conduits that connect terrestrial carbon cycling with downstream receiving environments. In large lakes, the utilization of river-transported carbon in biological production remains poorly constrained. Lake Athabasca, the eighth largest lake in Canada, receives inflow from the Athabasca River and a large boreal wetland, the Peace-Athabasca Delta. Radiocarbon (
