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

The formation and growth processes of octaneselenolate (C8Se) self-assembled monolayers (SAMs) on Au(111) from dioctyl diselenides were investigated by scanning tunneling microscopy (STM) as a function of vapor deposition time at 363 K. STM observations revealed unique surface features of the C8Se SAMs on Au(111) prepared at 363 K for 1 h, consisting of various types of narrow, bright molecular rows and broad, bright molecular rows with three-directional orientations. After increasing the deposition time from 1 and 6 h, interestingly, the structural quality of C8Se SAMs is greatly enhanced, showing the formation of tri-directional highly ordered domains with distinct domain boundaries on an entire Au(111) surface. The observed ordered phase can be described by a (2 × 2√7)rect packing structure with an arial density of 28.9 Å
