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
Caddisfly (Trichoptera) larvae assemble a variety of underwater structures using bioadhesive silk. The order is divided into two primary sub-orders distinguished by how the larvae deploy their silk. Foraging Integripalpia larvae construct portable tube cases. Annulipalpia larvae construct stationary retreats, some with suspended nets to capture food. To identify silk molecular adaptations that may have contributed to caddisfly diversification, we report initial characterization of silk from a net-spinner genus, Parapsyche, for comparison with the silk of a tube case-maker genus, Hesperophylax. Overall, general features of silk structure and processing are conserved across the sub-orders despite approximately 200 Ma of divergence: the H-fibroin proteins comprise repeating phosphoserine-rich motifs, naturally spun silk fibres contain approximately 1 : 1 molar ratios of divalent metal ions to phosphate, silk fibre precursors are stored as complex fluids of at least two types of complexes, and silk gland proteins contain only traces of divalent metal ions, suggesting metal ions that solidify the fibres are absorbed from the aqueous environment after silk extrusion. However, the number and arrangement of the repeating phosphoserine blocks differ between genera, suggesting molecular adaptation of H-fibroin through duplication and shuffling of conserved structural modules may correspond with the radiation of caddisflies into diverse environments. This article is part of the theme issue 'Transdisciplinary approaches to the study of adhesion and adhesives in biological systems'.
