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
In this study, based on the escalating demand for thermally stable scale inhibitors in high-pressure/high-temperature (HPHT) water-gas reservoirs, an organic-inorganic composite scale inhibitor (CT-5) was successfully synthesized via solution polymerization-mediated in situ intercalation using acrylic acid (AA), 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and diallyldimethylammonium chloride (DMDAAC) as monomers, with surface-modified montmorillonite (MMT) as reactive filler. Orthogonal optimization established ideal synthesis parameters, which including a reaction temperature of 75 °C, an initiator dosage of 0.6%, a solution pH of 7, a reaction time of 12 h, and a monomer ratio of m (AMPS): m (AA): m (DMDAAC): m (MMT) = 48:25:23:4. Moreover, the molecular structure and thermal stability of CT-5 were characterized by FTIR, XRD, and TG-DTG, as a result, the polymer intercalated MMT was successful, and CT-5 had a composite intercalation structure of organic polymer/inorganic montmorillonite, with a thermal decomposition temperature of 235.24 °C. Salt tolerance evaluation demonstrated robust performance under saline conditions. The scale inhibition mechanism of CT-5 was explored through scale inhibition rate testing, interlayer spacing testing at different temperatures, characterization of CaCO
