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
LncRNA-PTENP1 was reported to promote multiple myeloma cancer stem cell proliferation, and the G allele of rs7853346 polymorphism in lncRNA-PTENP1 was demonstrated to enhance the effect of lncRNA-PTENP1. In this study, we aimed to study the potential effect of lncRNA-PTENP1 and CCR2 mRNA polymorphisms on cognitive impairment in glioma patients. In this study, 279 glioma patients were recruited and grouped according to their genotypes of rs7853346 in PTENP1 and rs1799864 in CCR1. Pathogenic parameters were collected from patients before radiotherapy (month 0) or at month 1 and month 3 after radiotherapy to study the effect of rs7853346 and rs1799864 on cognitive impairment. Sequence analysis, luciferase assay, real-time PCR, and Western blot were performed to study the regulatory relationships between lncRNA-PTENP1, miR-18b, and CCR2. The glioma patient groups exhibited no significant differences concerning basic characteristics. However, the CG&GG/GG genotype alleviated radiotherapy-induced cognitive impairment by exhibiting the highest MMSE among the four groups. On the contrary, parameters including the severity of depression, bladder control, global health status, itchy skin, and weakness of legs all showed no difference among different patient groups at month 0, month 1, and month 3. Also, a long-term positive effect of CG&GG/GG genotype on role functioning and social functioning was also observed after radiotherapy. Compared with patients carrying the CC genotype of rs7853346, the expression of lncRNA-PTENP1 was reduced while the miR-19b level was elevated in patients carrying the CG&GG genotypes of rs7853346. Moreover, the expression of CCR2 mRNA was the highest in the CC/GA&AA group and the lowest in the CG&GG/GG group. Subsequent sequence analysis and luciferase assay indicated that miR-19b could bind to lncRNA-PTENP1 and 3'UTR of CCR2 mRNA, and the knockdown of lncRNA-PTENP1 led to evident up-regulation of miR-19b and down-regulation of CCR2 mRNA/protein in a cellular model, thus verifying the presence of the lncRNA-PTENP1/miR-19b/CCR2 mRNA signaling pathway. In conclusion, by studying the changes in the key parameters of glioma patients who were subjected to radiotherapy, we concluded that the rs7853346 polymorphism in lncRNA-PTENP1 and the rs1799864 polymorphism in CCR2 could independently affect cognitive impairment, while a more significant combined effect on cognitive impairment was exerted in glioma patients via the signaling pathway of PTENP1/miR-19b/CCR2.
