Differentially expressed profiles of LncRNAs in pterygium.
Article in BMC ophthalmology, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
objectiveTo do the differential expression of long noncoding RNAs (lncRNAs) in pterygium was screened by gene chip technology, and the differentially expressed lncRNAs HOTTIP and RP1-261G23.7 were studied to explore their possible mechanisms in the pathogenesis of pterygium.
methodsCollected 40 specimens from June 2016 to May 2017 that underwent surgery in the Ophthalmology Department of Yanjishan Hospital of Wannan Medical College, including 20 pterygium tissue specimens (6 males and 14 females, aged 47-84 years, mean age 68.1 years), 20 cases of normal nasal bulbar conjunctival tissue in patients with strabismus (9 males and 11 females, aged 41-88 years, mean age 61.6 years). Four samples from each group were randomly selected to detect lncRNA expression by high-throughput gene chip detection technology; lncRNA HOTTIP, RP1-261G23.7 and corresponding target genes HOXA13, VEGFA were screened by quantitative real time polymerase chain reaction (qRT-PCR) to verify whether there is a significant difference between the two groups, and to analyze the correlation between the expression of the target genes HOXA13 and VEGFA.
results(1) SPSS17.0 software was used for data processing in the experimental group and the control group. Gender and age were analyzed by the chi-square test. The statistical results were all P > 0.05, and there was no significant difference in statistics, (2) A total of 8271 differential lncRNAs were detected by high-throughput gene chip detection and compared with normal nasal bulbar conjunctival tissue in patients with strabismus. Among them, lncRNAs with a P-value < 0.05 and log fold change > 2 and Benjamini-Hochberg FDR correction (FDR < 0.05) had 612 upregulated genes and 743 downregulated genes. (3) The two highly differential lncRNAs were selected and verified by qRT-PCR. The results showed that lncRNAs HOTTIP and RP1-261 G23.7 and the corresponding target genes HOXA13 and VEGFA were highly consistent and highly expressed in the control group.
conclusions(1) LncRNAs are differentially expressed in pterygium; (2) Key lncRNA HOTTIP, RP1-261G23.7 may be new gene targets for pterygium.
