The impact of tractor drawbar height on performance and optimization using response surface methodology.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study explores the impact of tractor drawbar height (520, 530 and 540 mm from the ground) on key performance indicators, including pulling force, fuel consumption, pulling power and overall tractor efficiency. Present experiments were conducted on a special pulling power test track under controlled conditions at the Directorate of Agricultural Equipment and Machinery Test Centre of the Ministry of Agriculture and Forestry. Data were collected at different tractor forward speeds and performance parameters were modeled and optimized using Response Surface Methodology (RSM), a statistical approach widely used for multi-factor optimization. Present findings revealed that a drawbar height of 520 mm yielded the highest pulling force (47.4 kN) at a speed of 5.48 km h
