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

Information about behavior and habitat depths of Nautilus and Allonautilus species, the last remaining nautiloid cephalopod genera, is relevant both to paleobiologists trying to interpret the lives of extinct chambered cephalopods as well as to ecologists seeking to better understand the food webs of the Mesophotic Zone (200–800 m), fore-reef slope communities of the tropical Indopacific where these archaic animals live. One long-standing question is whether the extant nautiloid species live in deeper water than the many extinct species; a second is whether there are habitation depth differences of adult nautiloids compared to juveniles - either now or in the past. Using shell-mounted acoustic transmitters on seven different species in the two extant genera, and oxygen isotope shell thermometry on these same species as well as from fossils of 18 extinct fossil nautiloid species, we found regular, diurnal migration in only one species of each extant genus. Mature individuals in all tracked species of both genera were found to inhabit significantly shallower (and warmer) depths (~ 200 m) than the immature nautiluses and allonautiluses of the same populations (~ 350–400 m). Extinct nautiloid genera showed significantly warmer shell growth temperatures, with the single exception of Eocene through Miocene-aged species of the ammonoid-like genus Aturia, although diagenesis from not only ancient, but modern carbonates cannot be ruled out.
