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
backgroundPancreatic cancer (PanCa) is one of the most lethal cancers (survival ~ 12%). As the conventional therapeutic interventions are mostly futile, a deep understanding of the disease pathophysiology is an urgent need. Ion channels, located on cell membrane, contribute significantly to cancer hallmarks, through dysregulation of various ion translocation; however, the fundamental mechanisms remain uncertain.
methodsTo identify these oncochannels in Indian cohort of PanCa, we utilized 450 K data, published in our previous study, and identified potential pathways involved. Their expressions were evaluated using TCGA data and an independent Indian paired patient cohort (n = 20). The top genes were further validated using GEO and ScRNA seq dataset. Potential target ability of KCNJ5 was identified through molecular dynamic based drug designing.
resultsA set of 7 differentially methylated and differentially expressed genes of ion-channel proteins namely KCNJ5, CACNB2, KCNA3, KCNA6, RASA3, GABBR2 and CLIC5 were identified in Indian PanCa cohort only. KCNJ5 was significantly upregulated and associated with worse survival in Indian cohort, whereas downregulated in TCGA and other Caucasians patient populations. Two TFs controlling the KCNJ5 expression are POU2F1 and POU3F1. Few predicted small molecules targeting Kcnj5 are, Amiloride, Vernakalant hydrochloride, Dalfampridine, Glyburide and Levcromakalim. It also showed notable interactions with a steroidal anticancer agent, protodioscin.
conclusionAn onco-channel gene, KCNJ5 significantly upregulated, and showing adverse survival in highly expressed KCNJ5 group in Indian cohort of PanCa, can be targeted with Amiloride, Vernakalant hydrochloride, Dalfampridine, Glyburide Levcromakalim and protodioscin. This understanding can lead to novel target identification for PanCa therapy development.
