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

Water quality index (WQI) is used for representing the overall water quality in the form of a number to qualify its use for domestic, irrigation, industry or any other intended use. The present study involves determination of WQI using various physicochemical characteristics like pH, electrical conductivity, DO, BOD, nitrate nitrogen and total coliform for surface water samples for rivers Mahi, Sabarmati, Narmada and Tapi in Gujarat for the year 2016. The WQI for river Mahi was found between 30 and 50, for river Sabarmati between 42 and 65, for River Narmada between 28 and 52 and for river Tapi between 35 and 70. Based on WQI, it can be inferred that most of the surface water samples are in the category of good to poor. The quality of river water was good on upstream as compared with downstream. It can be inferred that the chief reason for decline in the quality of river water was discharge of sewage, industrial effluent and urban runoff.
