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

objectivesBlattella germanica, commonly known as German cockroach, is a globally prevalent household pest. The gut microbiota of B. germanica is influenced by multiple factors, yet their interactive effects remain poorly understood compared with other insect taxa. Midgut-specific microbial communities also remain understudied relative to whole gut or hindgut microbiota. In this study, 16S rRNA gene sequencing datasets were generated from midgut samples collected across varying life stages (adult and nymph), sexes (male and female), environmental origins (laboratory-reared and field-collected), and physiological states (fed and starved). DATA DESCRIPTION: Genomic DNA was extracted using the HiYield Genomic DNA isolation kit and amplified targeting the V3-V4 hypervariable regions of the 16S rRNA gene using primer pair 338 F/806R. Raw sequences reads were subsequently analyzed using QIIME2 pipeline following quality control and host decontamination. Taxonomic classification consistently identified the bacterial families Lactobacillaceae, Desulfovibrionaceae, Lachnospiraceae, Dysgonomonadaceae, Christensenellaceae, and Rikenellaceae across all treatment groups. Diversity indices (Shannon, Simpson, and Chao1) showed similar trends across samples, indicating stable patterns of microbial diversity and richness. These datasets support the exploration of specific midgut-associated taxa as potential targets for biological control strategies against B. germanica.
