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 aim of this study was to analyze the effects of Trichoderma asperellum on germination indexes and seedling parameters of lettuce cultivars. The trial was arranged in a completely randomized design with three cultivars (Cerbiata, Crespa Grand Rapids, and Mimosa), and two seed-treatment products (quality and organic) containing strain URM 5911 of Trichoderma asperellum plus a control group (untreated), with four repetitions. After seven days, six seedling characters were measured (shoot length, radicle length, total length, shoot diameter, radicle diameter, and seedling dry matter) and eight germination indexes were calculated (germination, first count, mean germination time, germination speed index, coefficient of velocity of germination, mean germination rate, Timson's germination index, and germination rate index). In general, regarding the germination indexes, the effect of the genotype factor predominated over the Trichoderma factor. The seedling characters showed significance for genotype × Trichoderma interaction for shoot length, shoot diameter, radicle diameter, and seedling dry matter. Such results demonstrate that the effects of Trichoderma asperellum on lettuce seedlings variate according to the cultivar used.
