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
To address the limitations of conventional CO₂-responsive plugging materials (fixed network structure, slow response, and poor long-term stability) in fractured reservoirs, a novel terpolymer hydrogel poly(acrylamide-co-2-acrylamido-2-methylpropane sulfonic-co-acid-methylenebis(acrylamide)) hydrogel, denoted as P(AM-AMPS-MDA) was designed via solution copolymerization. The hydrogel features a hybrid network of covalent crosslinks (from MDA with tunable ethyleneamino chain length n = 1-3) and CO₂-induced ionic clusters, with precise reactant ratios (AM: AMPS: MDA = 90:16:4, K₂S₂O₈:Na₂SO₃=2:1) ensuring reproducibility. Comprehensive characterizations (FTIR, TGA/DSC, rheology, strain sweep) confirmed its superior performance: the optimized MDA₂ hydrogel (n = 2) exhibits rapid CO₂ response (< 10 min), balanced swelling ratio (~ 18), high storage modulus (1790 Pa), and excellent thixotropy (> 90% recovery in 30 s). It maintains structural integrity at 80 °C (T
