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
Fenitrothion and methyl parathion residues pose significant public health risks. Efficiently extracting and real-time detecting pesticide residues in complex matrices remains challenging. This study presents an ultrafast enrichment and SERS detection approach, achieving rapid analysis of fenitrothion and methyl parathion in vegetable and fruit juices using a dual-functionalized microneedle. A point-of-use SERS-active microneedle was developed with rough silver covered with an Au layer for ultrafast electro-enhanced microextraction (EEM) and sensitive SERS response toward real-time monitoring. Applying a negative electric potential to the dual-functionalized microneedle, pesticide enrichment was accelerated, achieving a tenfold increase in efficiency over traditional static strategy. The EEM-SERS process can be completed in 5 min, with strong correlations noted between SERS intensity and pesticide concentrations (
