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
The Gini coefficient (GC), derived from the Lorenz curve in economics, has been widely applied to quantify the inequality in biological size distributions. Although the GC can be theoretically obtained from distribution functions, previous studies have not cross-validated the distribution-derived GC with empirically determined GC values for important traits such as the aboveground biomass of plants. Here, we used aboveground fresh mass (FM) of >2800 culms from 50 bamboo species with 29-142 culms per species to test whether the FM, as a representative of aboveground biomass, adheres to a normal, log-normal, two-parameter Gamma, or two-parameter Weibull distribution, and compared the distribution-derived GC with the observed GC calculated using the polygon method (denoted as
