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 beneficial effects of ammonium nitrate and potassium humate on carrots are well-documented. However, their impact on physiological and biochemical mechanisms under varying irrigation conditions still needs to be explored. Here, we investigated the effects of soil-applied ammonium nitrate and foliar-applied potassium humate on the physio-chemical characteristics and water use efficiency of carrot plants under three irrigation levels: 100%, 80%, and 60% of crop evapotranspiration (ETc). Carrot plants were treated with two rates of soil ammonium nitrate (200 and 250 kg N ha
