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

Al-Mahmoudia Canal is crucial for water supply in Egypt's Al-Beheira and Alexandria governorates, but it faces ecological challenges from pollution. This study examines plankton dynamics and water quality across four seasons at seven sites, analyzing microbiological contamination, heavy metals, turbidity, and nutrients. Phytoplankton abundance peaked in spring at Station 4, with seasonal variations linked to temperature and nutrients. Zooplankton showed seasonal diversity, with increased turbidity and nutrient levels in summer and autumn due to organic pollution. Heavy metal and microbial contamination also fluctuated seasonally, with fecal coliform levels exceeding safety limits. The study highlights pollution hotspots and emphasizes the need for ongoing monitoring and management to ensure sustainable water resource use in the Nile Delta.
