1 · What the graph read from it

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.

2 · The registry

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

To address the issues of missed seeding and seed stem jamming-factors that contribute to unstable performance in Pennisetum hydridum planting device, this study optimize the key components of the pre-cut stem planting device and evaluated its operational performance, thereby improving planting quality. Based on the results of preliminary experiments and discrete element method (DEM) simulation analysis, the critical components of the seed-metering device and their key influencing parameters were identified. Single-factor experiments were conducted to determine the appropriate parameter range. These were followed by a quadratic regression orthogonal rotation combination design for parameter optimization and the development of a response model for influencing factors. Finally, validation tests were performed to assess the effectiveness of the optimized parameters. The parameter optimization revealed that the optimal working parameter combination for the seed-metering device was: seed-cleaning rubber roller rotation speed (A) at 62.2 r/min, seed-filling rubber roller rotation speed (B) at 23 r/min, and conveyor belt operating speed (C) at 0.045 m/s. Under these conditions, the theoretically qualified seeding rate (Y
