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 a typical cincinnus, the neighboring two flowers are generally enantiomorphic, which leads to the pendulum symmetry of the entire cyme. While in a two-flowered Cannaceae cincinnus, the flowers develop the same chirality. In this study, we observed several abnormal cincinni of Canna indica that extended longer than their normal form, which presented a second enantiomorphic flower, thus reflecting a typical pendulum symmetry. The chirality change of the second flower was strongly associated with the position of the lateral cincinnus meristem, which determines the angle size of the cincinnus zigzag shift and may serve as a key factor controlling the formation of pendulum symmetry. We propose that alternating floral chirality and the concomitant pendulum symmetry are the essential characteristics of a typical cincinnus. Accordingly, Canna flowers with the same chirality are arranged in modified cincinni.
