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
The continuous rise in cost of fossil fuels and environmental pollution has attracted research in the area of clean alternative fuels for improving the performance and emission of internal combustion engines. In the present work, methanol and nitromethane were treated as a biofuel and investigations have been made to evaluate the feasibility of replacing diesel with a suitable diesel-methanol-nitromethane blend. For this, experimental investigations were carried out on a VCR diesel engine using diesel-methanol-nitromethane blends to determine the most favorable blending ratio and engine operating parameters for enhancing performance and reduce emissions. The best results of performance and emissions were observed with D-M5-NM2.5 blend (diesel 92.5%, methanol 5%, nitromethane 2.5%) at standard engine parameters. The improvement in engine performance (13% increment in BTE and 19.5% decrement in BSFC) and reduction in emission (smoke 26.47%, NOx 21.66%, and CO 14.28%) was found using D-M5-NM2.5 blend as compared to pure diesel at full load condition; however, HC emission was slightly increased by 10.71%. To find out the best suitable value of CR for D-M5-NM2.5 blend, experiments were further performed on different compression ratios by which higher compression ratio of 19.5 was found better under similar operating conditions. By increasing CR from 18.5 (standard) to 19.5, improvement in engine performance (BTE increased 3.8% and BSFC decreased 3.4%) and reduction in emission (smoke 10%, CO 16.67%, and HC 61.29%) were observed using D-M5-NM2.5 blend; however, NOx was found to be on slightly higher side with tolerable increment of 6.38%.
