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
Conventional micron sealants are unable to effectively seal nanopores and fractures in shale formations, and the development of new nanomaterials has now become a major research focus to address the instability of shale gas wells. In this paper, oil-based drilling fluids (ODFs) sealants named SMEB (poly(styrene-methyl methacrylate-ethyl methacrylate-butyl acrylate)) were synthesized by free radical polymerization. The SMEB has been characterized by Fourier transform infrared spectroscopy (FTIR), laser scattering analysis (LSA), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM). The effect of SMEB on the rheological properties of drilling fluids was evaluated by assessing the changes in the rheological parameters of ODFs before and after aging. In addition, the sealing performance of SMEB in ODFs was investigated by high-temperature, high-pressure (HTHP) fluid loss tests and HTHP dense core permeability tests. The results indicated that the particle size of SMEB ranged from 60.68 to 157.39 nm, with a median size of 89.62 nm. The initial decomposition temperature of SMEB was 334 °C, which was in line with the requirement of high-temperature resistance for materials used in shale gas wells. The addition of SMEB has minimal effect on the rheological properties of the drilling fluids and did not adversely affect its performance. At 150 °C and 3.5 MPa, the sealing efficiency of the simulated mud cake was 59.69% with a measured permeability of 0.77 × 10
