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
Glandular secreting trichomes of cultivated tomato (Solanum lycopersicum) produce a wide array of volatile and nonvolatile specialized metabolites. Many of these compounds contribute to the characteristic aroma of tomato foliage and constitute a key part of the language by which plants communicate with other organisms in natural environments. Here, we describe a novel recessive mutation called odorless-2 (od-2) that was identified on the basis of an altered leaf-aroma phenotype. od-2 plants exhibit pleiotrophic phenotypes, including alterations in the morphology, density, and chemical composition of glandular trichomes. Type VI glandular trichomes isolated from od-2 leaves accumulate only trace levels of monoterpenes, sesquiterpenes, and flavonoids. Other foliar defensive compounds, including acyl sugars, glycoalkaloids, and jasmonate-regulated proteinase inhibitors, are produced in od-2 leaves. Growth of od-2 plants under natural field conditions showed that the mutant is highly susceptible to attack by an indigenous flea beetle, Epitrix cucumeris, and the Colorado potato beetle, Leptinotarsa decemlineata. The increased susceptibility of od-2 plants to Colorado potato beetle larvae and to the solanaceous specialist Manduca sexta was verified in no-choice bioassays. These findings indicate that Od-2 is essential for the synthesis of diverse trichome-borne compounds and further suggest that these compounds influence host plant selection and herbivore community composition under natural conditions.
