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.

Abstract
One of the important links in the safety evaluation of sluices is the aseismic safety examination. In order to ensure the daily safe operation of sluices, it is necessary to conduct a normalized aseismic safety examination of sluices, and it is also necessary to study the aseismic safety examination of return sluices. Based on the application of ADINA finite element analysis software, a three-dimensional finite element model of the gate chamber structure is established, and the seismic response of the gate chamber structure is calculated and analyzed by the mode decomposition response spectrum method. The seismic safety of the gate chamber structure is evaluated comprehensively. The results show that 2.00 MPa of tension stress is generated at the junction of the pier and the gate. According to the structural mechanical method, the maximum tensile stress that can be endured is 4.41 MPa, which meets the safety requirements. There is a large tension stress zone between the elevator floor and some parts of the elevator, which far exceeds the standard tension strength value of the concrete moving shaft. Considering the safety, corresponding aseismic reinforcement measures should be taken. The structure of the gate chamber is nonslip and stable, and the safety factor is larger than the standard value of the Gate Design Specification (SL265-2016), which meets the safety requirements. The aseismic safety of the gate chamber structure meets the requirements of the "Standard for Seismic Design of Water Conservancy Buildings" (GB5127-2018), but it has safety defects and the aseismic grade is
