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 very low Earth orbit (VLEO), which includes orbits with altitudes of 100-450 km, has distinct advantages for remote-sensing spacecraft. Lower altitudes allow payloads with smaller dimensions, weight, and power to achieve performances similar to or better than larger payloads in higher orbits in remote sensing and Earth observation missions. The most important advantage of low orbits for optical imaging systems is the higher resolution these payloads can attain. The present paper systemically designs the very high-resolution imaging payload of an optical remote sensing satellite for operations in the VLEO. The aim of this design is to achieve a high spatial resolution of the optical imaging platform and reach a 1-m ground sampling distance (GSD) as reported. Therefore, considering an orbital altitude of 300 km and system calculations, the implementation of this method is described. The results obtained show that the proposed platform (VHR4) has better diffraction-limited ground resolution compared to several examples of operational satellite platforms under approximately equal orbital conditions. Also, by calculating and estimating the weight, power, and dimensions of the proposed imaging platform (VHR4), it is shown that the platform meets the requirements of a small satellite launcher in terms of weight, dimensions, and power.
