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

The causes of the transition from a greenhouse to an icehouse climate during the Early Mississippian (∼359-347 Ma), Carboniferous, marking the possible onset of the Late Paleozoic Ice Age (LPIA), remain an outstanding puzzle in Earth's climate history. This transition coincides with the mid-Tournaisian carbon isotope excursion (TICE). It is hypothesized that intensified continental silicate weathering during this period sequestered CO₂, boosted nutrients, and increased marine productivity, causing the positive TICE. However, direct evidence for enhanced continental weathering has been lacking. We present lithium isotope (δ⁷Li) data from two carbonate sections showing a ∼12‰ decline during TICE. Integrating δ⁷Li with carbon cycle models (GEOCLIM and COPSE) suggests silicate chemical weathering rates increased ∼30% with declines in weathering intensity during the TICE event, likely due to uplift or vegetation, ultimately reducing atmospheric
