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
An antenna-level bias-line-free, optically controlled pattern-reconfigurable planar antenna for wideband sub-6 GHz applications is presented. The proposed antenna consists of four tapered-slot radiating units arranged in a compact planar configuration and excited through a reconfigurable feeding network incorporating four light-dependent resistors (LDRs). By selectively illuminating LDRs using aligned LEDs, the corresponding feed arms are activated without DC-bias lines embedded in the antenna itself, enabling pattern switching while avoiding a complicated biasing network. The antenna supports ten radiation states, including four principal directions (0°, 90°, 180°, and 270°), four diagonal directions (45°, 135°, 225°, and 315°), and two dual-beam excitations (0°/180° or 90°/270°). Measured results show impedance matching over 3.3-6.7 GHz for all states (at -10 dB |S
