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

Aspergillus ear rot (AER) and aflatoxin contamination in maize threaten global food security and public health, with developing countries such as Bangladesh-where maize cultivation is rapidly expanding-being particularly vulnerable. This study evaluated the resistance of 25 commercially available maize hybrids to AER infection and aflatoxin accumulation under natural infection (field exposure without artificial inoculation) and artificial inoculation conditions. Hybrids were artificially inoculated using a toxigenic Aspergillus flavus strain (ES103) via the pin bar inoculation method to ensure uniform infection. Disease severity, kernel infection rates, and aflatoxin levels were assessed using standardized protocols. Significant variation was observed among hybrids, with disease severity ratings ranging from 5 to 7 on a 7-point scale, and no hybrid showed complete resistance. The hybrid 'Mohabeer' exhibited the lowest kernel infection rate (42.59%), the second-lowest total aflatoxin levels (536.31 ng/g total, 115.63 ng/g AFB
