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

Humic acid (HA) is known to improve phosphorus (P) availability in agricultural soils. Yet, the underlying mechanisms by which it influences the microbial community and subsequent P turnover remain unclear. In this study, a pot experiment was conducted using soil from a three-year Salvia miltiorrhiza (S. miltiorrhiza) cultivation system, in which the soil was amended with three HA concentrations (T1: 100-fold dilution, T2: 200-fold, T3: 400-fold) alongside an untreated control (CK). We determined P uptake by S. miltiorrhiza, soil P fractions, phosphatase activities, along with high-throughput sequencing of the microbial communities to specifically target those associated with P transformation. The results showed that HA application significantly enhanced root P uptake, with increases of 68.59% and 91.05% under T2 and T3, respectively. Consequently, soil Olsen-P content decreased by 19.19% and 15.20%, respectively, consistent with the depletion of available P under enhanced plant uptake. Soil P fractionation further revealed that HA application decreased inorganic P by 20.91% and 32.29%, respectively, under T2 and T3 treatments. Specifically, H
