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, a series of Ce3+, Eu2+, and Ce3+/Eu2+ co-doped oxyapatite Ba2La3(SiO4)2(PO4)O (BLSPO) phosphors were synthesized by the high-temperature solid-phase method. The crystal structure, luminescent properties and application prospects of the material were systematically studied. BLSPO crystallizes in the P63/m space group (No. 176), exhibiting experimentally confirmed high crystallinity. Photoluminescence and excitation spectroscopy analysis indicated that the BLSPO: Eu2+ phosphor could be effectively excited at 370 nm and was highly suitable for use in LED chips. The emission spectrum of BLSPO: Eu2+ phosphor shows a broadband emission peak of Eu2+ ions, with the peak at 510 nm. Through Gaussian fitting, this peak can be further fitted to two different emission centers at 507 nm and 536 nm, corresponding respectively to the M(I) and M(II) coordination environments within the BLSPO matrix. Under 315 nm excitation, the BLSPO:xCe3+ phosphor demonstrates a broad emission band peaking around 428 nm, with experimental results identifying 10 mol% as the optimal cerium ion doping concentration for maximal performance. In the BLSPO: Ce3+, Eu2+ co-doped system, the energy transfer mechanism between Ce3+ and Eu2+ was studied, and the energy transfer efficiency η value gradually increased from 0% to 86.96% with the increase of Eu2+ concentration. The mechanism of energy transfer is dipole-dipole interaction mechanisms. The thermal stability of the BLSPO:10 mol%Ce3+, 10 mol%Eu2+ samples was tested, and the sensitivity factors Sa and Sr reached their respective maximum values of 2.61 × 10− 2 K− 1 and 0.99% K− 1 at 480 K. The thermal stability test of BLSPO:5 mol%Eu2+ shows that at 420 K, the sample maintains 52% of its initial luminous intensity. Therefore, the CIE chromaticity coordinates of the green LED packaged with BLSPO:10 mol% Eu2+ phosphor is (0.263, 0.466), the CIE chromaticity coordinates of the w-LED are (0.335, 0.355), the color rendering index (Ra) is 92, and the correlated color temperature (CCT) is 5366 K.
