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

Sphingomyelin synthase (SMS) is a key enzyme in sphingolipid metabolism that catalyzes the synthesis of sphingomyelin (SM). The potential roles of SMS involved in the egg development and female fecundity on the tremendous pest mite Panonychus citri, however, remain unknown. In this study, we determined the function of sphingomyelin synthase gene in P. citri across different developmental stages. We silenced the PcSMS in adult females of P. citri via feeding on detached citrus leaves that absorbed dsRNAs. The survival rates and lifespan, along with the expressions of ROS and apoptosis genes were significantly changed. Additionally, fecundity and oviposition periods of P. citri were shortened. The expression levels of vitellogenin and its receptor genes were downregulated. Knockdown of PcSMS also affected egg hatching, resulting in developmental delays and egg lethal phenotypes. Our findings shed light on the metabolism underlying the biological functions of egg development and adult females fecundity of P. citri and render lipid metabolism the attractive target for biopesticide to control citrus spider mite.
