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

To explore the synergistic effects of biochar and nitrogen fertilizer on soil carbon emission and microbial diversity in acidic orchards were studied. A 300-day pot experiment was conducted, including control (CK), nitrogen fertilizer (N), 1% biochar (B1), 3% biochar (B3), nitrogen fertilizer with 1% biochar (NB1), and nitrogen fertilizer with 3% biochar application (NB3). After biochar and nitrogen fertilizer treatments, soil pH increased from 4.73 to 6.75 unit, soil organic carbon (SOC), mineral-associated organic carbon (MAOC) and particulate organic carbon (POC) contents increased 17.88%-41.14%, 31.95%-73.44% and 15.50%-48.90%, respectively, Dissolved organic carbon (DOC) content decreased by 33.56%-55.35%.
