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

In arid regions, agricultural water shortages and excessive nitrogen fertilization severely restrict the sustainable development of the tomato industry. To elucidate the effects of water-nitrogen interactions on the yield and photosynthetic physiological characteristics of tomatoes, a two-year (2024 and 2025) split-plot greenhouse experiment was conducted. The main plots evaluated two irrigation lower limits at 75% (W1) and 65% (W2) of field capacity (FC), and the subplots consisted of four nitrogen application rates: 0, 150, 300, and 450 kg ha
