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 possibility that odor stimuli trigger distinct Ca2+ elevations within the cilia of vertebrate olfactory receptor neurons (ORNs) is a widely proposed concept. However, because of the small size of the olfactory cilia, the existence and properties of such Ca2+ elevations and their role in odor transduction are still unknown. We investigate odor-induced Ca2+ changes in individual olfactory cilia from salamander using the Ca2+ indicator dye fluo-3 in combination with laser scanning confocal microscopy. Single brief applications of odor ligand produce highly localized Ca2+ elevations in individual cilia lasting for several seconds. These Ca2+ signals originate in the cilia and depend entirely on Ca2+ entry through ciliary cyclic nucleotide-gated ion channels. The odor specificity of the Ca2+ rises implies a receptor-operated mechanism underlying odor detection. Each of the cilia on a receptor neuron functions as an independent biochemical compartment that can detect odorants and produce a Ca2+ transient with remarkably uniform properties in terms of kinetics and odor specificity. The rate of recovery of the odor-induced Ca2+ transients matches recovery from a short-term form of odor adaptation. Application of the membrane-permeant intracellular Ca2+ chelator BAPTA AM eliminates this odor adaptation. The results indicate that an olfactory cilium serves as a basic functional unit at the input level of the olfactory system, controlling both the specificity and sensitivity of odor detection.
