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
Mosaic disease, caused by whitefly-transmitted begomoviruses, significantly threatens bitter gourd cultivation in India. This study identified and characterized the complete genome of coccinia mosaic Virudhunagar virus (CoMViV) from symptomatic bitter gourd samples collected in Oddanchatram block of Dindigul district, Tamil Nadu, using rolling circle amplification and sequencing. A loop-mediated isothermal amplification (LAMP) protocol was optimized by targeting regions of the CoMViV AV1 and AV2 genes. The LAMP assay demonstrated exceptional sensitivity, detecting as little as 10 fg of viral DNA, a 100-fold improvement compared to PCR. Specificity tests confirmed that the LAMP assay exclusively detected CoMViV in bitter gourd, with no cross-reactivity with other begomoviruses. Real-time LAMP assay produced a distinct annealing peak at 86.5 ± 0.5 °C. Furthermore, viral quantification revealed a maximum viral titer of 3.2 × 10⁹ copies per µl in infected leaf samples. While both LAMP and PCR assay successfully detected CoMViV in infected tissues, the LAMP assay offers advantages including simplicity, rapid, and sensitivity. This optimized LAMP assay provides a valuable tool for differentiating CoMViV from other begomoviruses infecting bitter gourd crop, offering an improvement over existing PCR assay. To the best of scientific knowledge, we, for the first time, demonstrate the LAMP assay for the detection and quantification of CoMViV in bitter gourd plants.
