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

Nutrients needed to fuel the processes of growth, development, and reproduction, and to form the proteins in the cocoon, are derived from the larval stage. The amount of leaf ingested in the fifth instar silkworm larvae accounted for about 85% of the whole instars. Nutrients were absorbed following digestion in the digestive tube. We previously reported the successful identification of 227 silkworm larval digestive juice proteins, wherein most of the genes of the identified proteins had high expression features in the midgut, and 30 of them were midgut-specific genes. We chose 30 genes and detected their expression characteristics in the digestive tube, and investigated the developmental expression profiles in the midgut of silkworm larvae from the day-3 fourth instar to the wandering period, as well as the expression dynamics after the 20-hydroxyecdysone (20E) treatment. The genes were specifically expressed in the larval digestive tube. The expression of
