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.
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
Domestication of cereal crops, such as maize, wheat and rice, had a profound influence on agriculture and the establishment of human civilizations. One major improvement was an increase in seed number per inflorescence, which enhanced yield and simplified harvesting and storage. The ancestor of maize, teosinte, makes 2 rows of kernels, and modern varieties make ∼8-20 rows. Kernel rows are initiated by the inflorescence shoot meristem, and shoot meristem size is controlled by a feedback loop involving the CLAVATA signaling proteins and the WUSCHEL transcription factor. We present a hypothesis that variation in inflorescence meristem size affects kernel row number (KRN), with the potential to increase yield. We also show that variation in the CLAVATA receptor-like protein FASCIATED EAR2 leads to increased inflorescence meristem size and KRN. These findings indicate that modulation of fundamental stem cell proliferation control pathways has the potential to enhance crop yields.
