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
A high sensitivity temperature sensor based on polymer and liquid modified anti-resonant reflection principle is proposed. The sensor is made of a section of liquid-filled and UV-curable adhesive coated silica capillary, sandwiched between single mode fibers. The guiding mechanism of the waveguide is affected by both the liquid inside the hollow core, and the adhesive outside the silica cladding. The location of the resonant dips are influenced by the refractive index (RI) of the liquid, while the fringe visibility (resonant strength) is tuned by the both the liquid and the adhesive. By carefully selecting the refractive index value of the infiltrated liquid, and controlling the curing time of the adhesive, sharp resonant dips can be obtained. The sensor exhibits very high temperature sensitivity against temperature. A high sensitivity of 3.369 nm/°C is achieved with an infiltration index of 1.39, in the temperature range from 25 °C to 60 °C. The detection limit of the proposed sensors are 0.04 °C. Moreover, the temperature sensitivity of the sensor is found to be decreasing with the order of resonance. The sensor is easy to fabricate and cost effective, and is applicable in both dry and wet environments, which can find wide applications in biochemical and pharmaceutical industry.
