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

key messageWe resolved that SlMYC2 positively regulated tomato leaf senescence by inhibiting ROS scavenging capacity and exacerbating oxidative damage and PSII functional decline using a darkness-induced senescence model. Tomato leaf senescence seriously affects its yield and quality. Jasmonic acid (JA) signaling can promote tomato leaf senescence, but the mechanism is unclear. SlMYC2, as a core transcription factor in JA signaling, may play a role in regulating leaf senescence. Therefore, this study used SlMYC2 overexpression and silencing lines to systematically analyze the mechanism of SlMYC2 regulation of leaf senescence through a darkness-induced senescence model. The results showed SlMYC2 accelerated the leaf senescence process in tomato by increased chlorophyll degradation and malondialdehyde accumulation in SlMYC2-OE lines after dark treatment, and the expressions of senescence-related genes SlSGR1, SlSAG12, and SlSAG15 were significantly upregulated. At the photosynthetic physiological level, SlMYC2-OE caused damage to photosystem II (PSII) function, with a significant decrease in maximum photochemical efficiency (F
