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
backgroundRecent studies have shown that the abnormal expression of long-chain non-coding RNAs (lncRNAs) can significantly affect the biological function of trophoblast cells and lead to the occurrence of preeclampsia (PE). This study explores the expression of lncRNA LINC00922 in PE and its effect on the function of placental trophoblast cells, along with the corresponding molecular mechanism, providing a theoretical basis and molecular target for understanding the occurrence, early diagnosis, and targeted therapy of PE.
methodsFluorescence quantitative PCR was used to detect the expression of LINC00922 in 30 cases of PE tissues and normal tissues. The CCK-8 assay, clone formation experiment, and flow cytometry were used to detect the effects of LINC00922 knockdown or overexpression on the proliferation, colony formation, and cell cycle of HTR-8/SVneo placental trophoblast cells. The Transwell assay was used to detect the effects of LINC00922 knockdown or overexpression on the invasion and migration of HTR 8/SVneo cells, and western blot was used to detect the expression of cell cycle-related proteins and invasion and migration-related proteins.
resultsLINC00922 was highly expressed in PE tissues. Knockdown of LINC00922 significantly inhibited the proliferation, invasion, and migration of HTR-8/SVneo cells, along with colony formation and the ability to induce cell cycle arrest in the G0/G1 phase. However, overexpression of LINC00922 had the opposite effect. Knockdown or overexpression of LINC00922 significantly affected the expression of cell cycle-related proteins cyclin-dependent kinase 2 (CDK2), G1/S-specific cyclin-D1 (Cyclin D1), p21, proliferating cell nuclear antigen (PCNA), matrix metallopeptidase 9 (MMP-9), vimentin, and E-cadherin, but had no significant effect on the expression of matrix metallopeptidase 2 (MMP-2).
conclusionsLINC00922 was highly expressed in PE, and functional experiments showed that LINC00922 could significantly affect the proliferation and invasion abilities of placental trophoblast cells, suggesting that LINC00922 may play an important role in the occurrence, early diagnosis, and treatment of PE.
