1 · What the graph read from it

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.

2 · The registry

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

Open metal sites (OMS) serve as crucial active sites in numerous applications, including hydrogen isotope separation, highlighting the importance of developing targeted synthesis strategies for OMS-containing frameworks. Unlike defect-engineered approaches that generate disordered OMS, synthesizing frameworks with an ordered distribution of OMS remains highly challenging yet is essential for efficient separation. Guided by the topological simplification process-which abstracts connectivity while overlooking coordination geometry-this study introduces a strategy to construct metal-organic frameworks (MOFs) with ordered OMS by reducing linker symmetry. By employing bent linkers with lower axial symmetry, rather than linear linkers of equivalent topological connectivity, OMF-2 (OMF = Open-Metal Framework) was synthesized, a pcu 8-connected framework featuring four OMS per cluster, thereby validating the approach. Remarkably, OMF-2 demonstrates exceptional hydrogen isotope separation performance, with an ideal adsorbed solution theory (IAST) selectivity of 7.7, a cryogenically programmed desorption (CPD) selectivity of 6.6, and a breakthrough test selectivity of 2.3 for D
