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

Determining the current presence of liquid water on Mars has important hydrological, geological, and astrobiological implications. Recurring slope lineae (RSL), as features presently developing on Mars, have been suggested to result from transient flows of liquid water or dry particles. This study presents a time-series analysis of RSL in Palikir and Raga craters on Mars, using datasets collected during Mars years (MY) 32 to 36. Our results unveil a significant increase in RSL after the global dust event in MY 34 compared to other years and its dependence on surface temperatures on sun-facing slopes. Further investigation into the relationship between RSL and bedrock outcrops suggests a plausible scenario for RSL formation based on the melting of bedrock aquifers. A landslide observed close to the RSL-rich region may have been formed by the slope's destabilization due to groundwater influx, which could indicate a water-related origin for the RSL. This outcome is further supported by spectral evidence of the presence of hydrated salts in RSL during the summer and their absence in autumn. Our results provide a possible scenario for RSL formation and support the hypothesis that RSL may be related to contemporary water activity on Mars.
