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

Cultivar improvement is an important means of enhancing drought resistance in maize. Investigating the reasons for enhanced drought resistance in modern cultivars and screening drought tolerance indicators are of great significance for the breeding of drought-tolerant maize cultivars in China. This study first assess the drought resistance in cultivars from different eras and its influencing factors and then examines the relationship between drought resistance and phenotypic indexes to screen for drought resistance indicators useful for breeders in selecting drought-resistant cultivars. An investigation of drought resistance was performed in a rainout shelter in Hengshui, Hebei, over the 2018 and 2019 growing seasons. The experiment employed a split-split plot design, which comprised nine maize hybrids representing different eras and three water treatment levels (full irrigation, moderate drought, and intense drought). Grain yield and phenotypic indexes of different maize hybrids from different eras (1970s to 2010s) were compared under different water treatments. Maize yield showed a significant linear increase with the year of release (p < 0.01). The maize yield of modern cultivars (Cluster III) under full irrigation, moderate drought, and intense drought was 9.08 t ha
