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
purposeThe physical seed priming methods are becoming promising due to their lower application costs and greater safety compared with the chemical methods. Although many benefits of microwaves as a physical treatment have been proven for humans and animals, there are not enough studies to highlight their importance for plants, especially under stressful conditions such as salinity. Therefore, possibility of using microwaves to enhance salt tolerance of Gypsophila paniculata plants was investigated.
methodsSeeds of G. paniculata were exposed to microwaves for three exposure times (5, 10 and 15 s), in addition to the control treatment (without microwave treatment). Seeds were then sown in pots and the produced plants irrigated with saline water at salinity concentrations of 0, 1000, 2000 and 4000 mg L
resultsRaising concentration of salts in the irrigation water resulted in considerable declines in G. paniculata vegetative growth and flowering traits, leaf nutritional status, plant pigments, and carbohydrates percentage while proline, catalase activity and malondialdehyde increased. Plants produced from microwaved seeds for 15 s exhibited the maximum increases of vegetative growth and flowering traits, leaf nutrients content, plant pigments, carbohydrates percentage, proline, and catalase activity with significant reduction in malondialdehyde. Under different salinity levels, microwaving seeds for 15 s was the efficient treatment for improving growth, flower quality, nutrients homeostasis, biochemical constituents and oxidative stress indices G. paniculata plants.
conclusionThe sensitivity of G. paniculata to salinity was reduced by applying microwave technology, as the physiological balance was regulated, thus improving the growth and flowering features. Microwave influences may contribute in the metabolism and biosynthesis of osmolytes and antioxidant defensive modes under salt stressful. Accordingly, sowing the microwaved seeds for 15-second as a novel seed priming could be practiced to enhance salt tolerance of G. paniculata crop grown in arid regions.
