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

The two-spotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a major constraint to cotton production worldwide. The age-stage, two-sex life table approach provides a comprehensive assessment of arthropod population dynamics by incorporating stage differentiation, variable developmental rates, and the contribution of both sexes to population growth. This method provides more accurate estimates of demographic parameters and host suitability than conventional female-based life tables. Yet comparative demographic responses of T. urticae to cotton varieties remain insufficiently characterized in Bangladesh. Therefore, this study evaluated the life-history traits and population dynamics of T. urticae on five cotton varieties (CB-12, CB-14, CB-15, HC-1, and M-1) using the age-stage, two-sex life table approach under controlled laboratory conditions. The host plant significantly influenced development, reproduction, and demographic parameters. Development from egg to adult ranged from 14.92 days on M-1 to 16.34 days on CB-14. Fecundity was highest on CB-15 (72.38 eggs female
