Analysis of Tight Junction Formation and Epithelial Barrier Integrity by Calcium Switch and TEER Measurement.
Article in Methods in molecular biology (Clifton, N.J.), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Tight junctions, which are located on the apical side of epithelial cells, are key components of epithelial intercellular junctional complexes. Tight junctions seal the space between neighboring cells and act as a semipermeable barrier, preventing the paracellular transport of ions and molecules. The tight junctions are calcium-dependent as their disassembly can be triggered by the depletion of calcium ions, and the subsequent addition of calcium promotes the formation of tight junctions and the restoration of their barrier function. This reversible process, known as the calcium switch, is often used to study tight junction dynamics. This chapter describes the calcium switch protocol for disrupting and reestablishing tight junctions using MDCK cells as an in vitro model. It also provides protocols for evaluating tight junction formation and integrity using the noninvasive, quantitative transepithelial electrical resistance (TEER) assay.
