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
Accurately assessing the low-temperature performance of asphalt materials is important for asphalt pavements in cold regions with large temperature differences. This study investigates the effects of freeze-thaw cycles on the low-temperature performance of basalt fiber-rubber powder composite modified asphalt mixtures (BRMAM). The influence of basalt fibers content on the mechanical properties of asphalt binder was characterized through basic property tests and bending beam rheometer (BBR) assessments. A freeze-thaw cycle process was designed to stimulate the more realistic climate. The deterioration of low-temperature performance and freeze-thaw damage mechanism were analyzed by the splitting tensile test, three-point bending test and semi-circular bending (SCB) test. Methods suitable for evaluating BRMAM's low-temperature performance were compared and explored. The results indicate that when fiber content was about 0.3%, the reinforcement effect of basalt fibers on asphalt material was more pronounced. As freeze-thaw cycles progress, the impact of frost heave force on the cracking resistance significantly increases, while the influence degree gradually decreases. Excess fibers reduced the interfacial bond between rubber powder modified asphalt and aggregate. When fiber content is between 0.2 and 0.4%, BRMAM demonstrates optimal low-temperature performance and the least sensitivity to freeze-thaw cycles. After 30 cycles, the TSR of BRMAM with 0.3% basalt fiber even reached 47.6%.
