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

The utilization of native lunar soil and recycled organic waste as primary resources will reduce the reliance on terrestrial inputs and improve the self-sufficiency of bioregenerative life support systems (BLSSs) in future lunar bases. A major question to address is the suitability of lunar soil for plant growth and how soil agronomic performance is affected by biochar. Biochar treatments increased the organic matter content and promoted greater availability of N, P, and K in the simulated lunar soil. It also reduced the bulk density and facilitated the optimal distribution of plant roots. Redundancy analysis indicated that the physical and chemical properties of soil pH, alkali-hydrolyzable nitrogen (AN), and total nitrogen (TN) content might be critical factors influencing lettuce growth. The aforementioned analysis suggested that the optimum rate of biochar addition to improve simulated lunar soil is 3%. The results showed that the utilization of pyrolysis for treating solid waste in BLSSs has significant potential, with biochar enhancing the properties of the simulated lunar soil.
