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
This study investigates the physiological and biochemical stress responses of the microarthropod Xenylla welchi to different sublethal doses of lead-contaminated garden soil in microcosms, aiming to assess the impact of metallic contamination in tropical ecosystems. 24-hour LC50 for lead acetate was determined to be 2653.23 mg/kg. Chronic exposure to various sublethal concentrations (1/2, 1/4, 1/6, and 1/8 of LC50) revealed significant reductions in exuvia production, fecundity, and lifespan, particularly at higher lead concentrations. Several biochemical parameters were assessed to further understand lead-induced stress responses. A marked decrease in glutathione (GSH) levels indicated oxidative stress, while glutathione-S-transferase (GST) activity displayed temporal variations, initially increasing and then declining with prolonged exposure. Acetylcholinesterase (AChE) activity was consistently inhibited across the treatment groups, reflecting neurotoxicity. Additionally, metallothionein (MT) levels were significantly elevated after extended lead exposure, suggesting an adaptive response to metal detoxification. The cumulative responses of Xenylla welchi suggest that they could be reliable biomarkers for assessing the ecological impact of lead pollution in soil ecosystems, highlighting their potential usefulness in monitoring heavy metal contamination.
