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
Objective: Global aging has led to a steady rise in the number of older adults suffering from the first-episode depression with cognitive impairment (FEDCI), which imposes a huge medical and financial burden on patients and their families. The aim of this study was to explore the influence of the NOS3 rs1799983 polymorphism on the FEDCI. Methods: A total of 224 first-episode depression (FED) and 295 FEDCI patients were included in the study, whose serum levels of NOS3 and inflammatory factors were detected by RT-qPCR. The TaqMan probe method was used to detect the rs1799983 genotype distribution. GDS-15 and HAMD-17 were used to detect the level of depression, and MMSE was used to detect cognitive impairment. Chi-square analysis was used to detect the correlation between clinical characteristics and NOS3 expression. Risk factors for FEDCI were analyzed by logistic regression. Results: The NOS3 expression decreased, and TNF-α, IL-1β, and IL-6 expression increased in the FEDCI group, and these two factors' expression was negatively correlated. The MMSE score was positively correlated with the NOS3 expression. The TT genotype and T gene frequency in the distribution of FEDCI patients accounted for a high percentage, with the TT genotype being the causative genotype. Education, GDS-15, HAMD-17, and MMSE are correlated with the NOS3 expression. MMSE, NOS3 expression, and the rs1799983 TT genotype were risk factors of FEDCI. Conclusion: The NOS3 expression was decreased in FEDCI, and the rs1799983 TT genotype was pathogenic. The NOS3 rs1799983 polymorphism in FEDCI provided a potential diagnostic and therapeutic target.
