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

Thymoquinone (TQ), a bioactive compound found in Nigella sativa seed oil, has been widely studied for its therapeutic potential. In this study, a new, sensitive, and cost-effective method was developed for TQ determination using square-wave voltammetry (SWV) with an environmentally friendly carbon paste electrode. Due to the morphology of the TQ oxidation signals, three calibration curve construction methods were tested, namely, based on: current height, peak area and cumulative voltammetry concept. The broadest linear range was established when calibration curve was constructed on the basis of TQ peak current height (LOD 8.9 nmol·L
