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.

Abstract
The passive suspension system based on centralized hydraulic sources suffers from prominent issues such as large space occupancy, low energy efficiency, maintenance difficulties, and insufficient overall performance. To address these issues, this paper innovatively proposes design solutions and control strategies for multiple suspension systems based on distributed hydraulic sources, specifically tailored for heavy-duty special wheeled vehicles. A semi-active suspension system is developed based on both PID control strategy and sky-hook control strategy, which enhances suspension performance under the constraints of limited cost and minimal structural changes. A detailed comprehensive performance simulation model is established, and simulation analysis is conducted under different driving states and road surface conditions. The results indicate that the PID control strategy performs better under dynamic operating conditions such as curves, acceleration, and braking, while the sky-hook control strategy performs better when the vehicle traverses on Class C-F road surfaces. To further enhance the suspension system's performance, active and slow-active suspension systems are designed. By actively applying control forces, the limitations of the semi-active suspension, which can only respond passively, are overcome. Through the integration of road surface recognition technology, the systems can sense the road surface conditions ahead in real time and convert them into control commands in a feedforward form. This significantly improves the dynamic performance of the suspension system and reduces the performance requirements on posture stabilization devices for onboard weapons and other equipment. In terms of vehicle body deflection, vehicle body acceleration, and dynamic tire load, the relevant indicators for the active suspension are reduced to 2.5%, 7.2%, and 7.3% of those for the semi-active suspension, respectively, while the relevant indicators for the slow-active suspension are reduced to 46.3%, 31.4%, and 31.5% of those for the semi-active suspension, respectively.
