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

A popular way to measure the surface areas of porous solids involves fitting a small section of the experimentally measured liquid nitrogen, liquid argon, or moisture adsorption isotherm to the Brunauer-Emmett-Teller (BET) model. A small section is used, because the BET isotherm's shape differs dramatically from the experimental isotherm's shape. Several studies proposed consistency criteria to automate choosing the small isotherm portion fitted during BET analysis. In this article, we follow a different approach that constructs a general-purpose model adsorption isotherm with enough flexibility to fit the experimental adsorption isotherm across its entire pressure range. This enables the whole adsorption isotherm to be used to extract surface areas of porous materials. Our MD model isotherm is formulated to apply to fluids both below and above the critical temperature and critical pressure. Mathematical derivations revealed this isotherm is non-negative, monotonically increasing with x
