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 investigated the spatial and temporal variations in heavy metal concentrations in the water of the Esa-Odo Reservoir, located in Osun State, Nigeria. Surface water samples were collected from three designated stations using an improvised water sampler between March 2018 and December 2019, covering two distinct seasons. The Atomic Absorption Spectrophotometric (AAS) method was employed to analyse the acidified water samples (two millilitres of concentrated HNO
