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.
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
Glyphosate-based herbicides (GBHs) are widely used and contribute to soil, water, and air contamination. Despite differing assessments of its carcinogenic potential, glyphosate toxicity may be enhanced by the co-formulants (adjuvants) used to improve its effectiveness. In this study, we investigated the genotoxic effects of glyphosate, alkyl dimethyl betaine (adjuvant A), and polyethoxylated tallow amine (adjuvant B) on human peripheral white blood cells using a cytokinesis block micronucleus (CBMN) assay. The experiments tested Glyphosate (0.1, 1, 10, and 100 μM) and adjuvants (at concentrations matching their levels in respective GBHs) in whole blood samples. The samples were exposed for 4 and 20 h with and without S9 metabolic treatment. The results showed that glyphosate and adjuvant A caused a statistically significant increase in the frequency of binucleated cells with micronuclei (BNMN%) only at 100 μM after 4-hour exposure without S9 treatment. Adjuvant B, however, induced a statistically significant increase in BNMN% starting at 1 μM after 4-hour exposure without S9 treatment. No significant effects were observed after 4 h of exposure with S9 or 20 h of exposure, with or without S9. The proliferation index (PI) showed no significant changes. This study concluded that the co-formulants in GBHs can induce genotoxic effects at low concentrations and short exposure times. This indicated that some surfactants in GBHs may be more toxic than glyphosate.
