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
Wheat, a staple food crop globally, faces the challenges of limited water resources and sustainable soil management practices. The pivotal elements of the current study include the integration of activated acacia biochar (AAB) in wheat cultivation under varying irrigation regimes (IR). A field trial was conducted in the Botanical Garden, University of the Punjab, Lahore during 2023-2024, designed as a split-split-plot arrangement with RCBD comprising three AAB levels (0T, 5T, and 10T, T = tons per hectare) three wheat cultivars (Dilkash-2020, Akbar-2019, and FSD-08) receiving five IR levels (100%, 80%, 70%, 60%, and 50% field capacity). Biochar amended soil showed improved BET surface area, pore size, and volume. Carbon recovery (45%) and carbon sequestration capacity (49%) of 10T-AAB amended soil were better than non-amended soil (0.43% and 0.13%, respectively). The 10T-AAB amendment significantly improved the soil's microporosity and water retention capacity, increasing it by 1.1 and 2.2 times, respectively. Statistical analysis showed that a reduction in IR negatively affected plant growth and yield. The 10T-AAB levels significantly increased sugar contents (14%), relative water content (10-28%), membrane stability index (27-55%), and photosynthetic pigments (18-26%) of wheat leaves under deficit irrigation among all the cultivars. Maximum stress markers (catalase, proline, peroxidase, and superoxide dismutase) were observed from Akbar under 50% irrigation with 0T-AAB, and the least were observed from 50% irrigated Dilkash-2020 with 10T-AAB amended soil. Among cultivars, Dilkash-2020 was observed to be the best for maximum yield, followed by FSD-08 and Akbar-2019, respectively. When compared to other IR levels, 10T-AAB amended soil had the highest yield enhancement (12, 11, and 9.2 times for Dilkash-2020, FSD-08, and Akbar-2019, respectively). Hence, AAB enhanced wheat production by improving soil properties, drought resilience, and yield attributes.
