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

Silicification in carbonate deposits refers to a diagenetic process in which silica replaces carbonate minerals, which are typically associated with hydrothermal fluids. During silica deposition under hydrothermal conditions, quartz crystallites often form on the surfaces of microorganisms, acting as nucleation sites. This silica replacement involves the simultaneous chemical transformation of the original skeletal materials, followed by precipitation. Organic matter-filled silica sphere-like structures were identified in the thin sections from the Barra Velha Formation chert (Santos Basin, Brazil), by the use of the Raman spectroscopy mapping technique and Scanning Electron Microscopy (SEM). The remaining organic matter showed two typical bands in the first-order Raman spectrum, i.e., the D-band located at approximately 1350 cm
