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 the Drosophila antenna, olfactory sensilla are the fundamental unit of odor detection and processing. Sensilla house one to four olfactory neurons enwrapped by three distinct support cells: thecogen, trichogen, and tormogen cells. While olfactory neurons and their odor receptors have been extensively studied in Drosophila, and increasingly in other insect species, much less is known about the support cells and their functional roles within the mature sensillar unit. A critical barrier to studying their function has been the lack of validated markers to distinguish and manipulate these cells in adult flies. Here, we systematically identify and characterize tools to differentially label specific olfactory support cells in the antenna, including sv
