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
Identifying loci conferring resistance to geminiviruses is an on-going priority in diverse crop species. Multiple geminivirus resistance quantitative trait loci (QTLs) and genes have been described, including most recently DNA polymerase delta subunit 1 (POLD1) in both cassava and tomato. From this, we hypothesized that POLD1-mediated resistance is present in a broad range of plant species. An analysis of multiple species with published geminivirus resistance QTLs was done to identify species with POLD1 variation consistent with known resistance alleles. Further, allele mining of over 7,000 accessions across 10 different genera, from both dicots and monocots, identified additional substitutions in key regions of the POLD1 protein as possible novel resistance alleles. These results provide evidence that POLD1 variation is a source for geminivirus resistance in diverse plants including cotton, soybean, squash, wheat, and maize.
