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 this paper, we describe the synthesis of a cDNA library from the vegetative shoot apical meristem and the analysis of clones selected from it. Using in situ hybridization, we characterized the patterns of expression of these genes in the tomato shoot apical meristem, as well as the patterns obtained from other sources. The results from the analysis of 15 cDNAs indicated the following six main patterns of gene expression in the shoot apical meristem: overall expression, zero expression, expression limited to the epidermis, expression excluded from the epidermis, punctate expression, and expression elevated in the flanks of the meristem. The patterns observed and the nature and number of the genes showing these patterns necessitate a reinterpretation of the models of meristem structure and function. In particular, the data suggest a compartmentation within the shoot apical meristem based on the spatial expression of particular subsets of genes. This paper also reports on the specific and precise criteria essential for the correct identification of meristem-specific gene expression. The data give new insight into the molecular organization of the shoot apical meristem and provide the framework for a detailed dissection of the factors controlling this organization.
