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

Cheyletus malaccensis (Oudemans), a generalist predatory mite, is a highly promising biocontrol agent applied for stored products pests management in grain storage systems. To optimize its field deployment, this study evaluated the population dynamics of C. malaccensis and Liposcelis bostrychophila (Badonnel) under varying predator-prey ratios (PPRs: 1:9, 1:5, 1:3, 1:1, 3:1) at 26.0 ± 0.1 °C and 75.0 ± 0.5% relative humidity in simulated grain storage environments. During the 49-day post-release period, the peak population reduction rates of L. bostrychophila at four PPRs (1:5, 1:3, 1:1, 3:1) reached 74.87%, 76.61%, 87.10%, and 95.90% respectively, whereas the 1:9 PPR treatment resulted in progressive pest population growth. Conversely, C. malaccensis population establishment rates increased exponentially with decreasing PPRs, peaking at 1,161.11% (1:9 PPR). These findings demonstrate a density-dependent trade-off: higher PPRs maximize short-term pest suppression, while lower ratios enhance long-term predator persistence. Therefore, we propose a two-phase deployment strategy: (i) preventive low-density releases (PPR < 1:5) prior to pest outbreaks to establish mite populations, and (ii) threshold-triggered supplementary releases based on real-time pest monitoring to achieve economical and long-term control of stored grain pests.
