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 deposition of nutrients from the atmosphere into the ocean has been recognized as an important pathway for marine ecosystems. We measured the photosynthetic rates of phytoplankton for surface seawater sampled at three sites with nitrogen-nutrient-depleted condition in the subtropical, western North Pacific in March 2021 during the R/V Mirai cruise using a photosynthesis-irradiance experiment, to investigate the impact of atmospheric inorganic nitrogen deposition. The maximum photosynthetic rates at the Sites 1 (25-00°N, 145-00°E), 2 (26-30°N, 135-00°E), and 3 (28-00°N, 135-17°E) were 5.56±0.15, 6.91±0.17 and 7.38±0.15 mg-C (mg-Chl-a)
