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

This study explores the phosphorite deposits from the Lower Member of the Duwi Formation in Egypt, which forms part of the Mediterranean phosphorite belt extending from Africa to Asia. Detailed petrographical, mineralogical, and geochemical investigations were carried out to shed light on the prevailing physicochemical conditions and diagenetic history of these deposits. They are classified into three east-west trending belts, with significant economic occurrences located in the central facies belt, particularly along the Nile Valley and Red Sea shoreline. Geochemical analyses indicated that these phosphorites are predominantly composed of CaO (avg. 35.83 wt%) and P
