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
Bush-crickets exhibit remarkable auditory diversity, having a pair of tympanic membranes (tympana) on each foreleg. These tympana could be exposed or covered by cuticular flaps known as auditory pinnae. These membranes receive sound directly and via an acoustic tracheal tube. Despite extensive research on auditory tuning, the relationships between the tympanal morphology, body size, and acoustic traits of bush-crickets remain unclear. In this study, micro-computed tomography reconstructions, artificial-intelligence-assisted segmentation, and phylogenetically informed comparative regressions in 18 selected bush-cricket species were used to investigate how tympanal surface area and mean cross-sectional thickness relate to pronotum length (a proxy for body size), carrier frequency, and the presence of auditory pinnae. Tympanal surface area scaled positively with pronotum length, whereas thickness was independent of size. Carrier frequency showed a weak negative relationship with tympanal thickness, although this association was not statistically significant. Among 14 species with well-developed auditory pinnae, tympanal dimensions showed no correlation with peak resonance frequency, suggesting that pinnal cavity resonance and tympanal morphology are not tightly correlated and may evolve independently. Across species, the presence of pinnae was not associated with differences in tympanal surface area, although unilateral pinnae were linked to thicker tympana. Within the 4 unilateral species, the pinna-covered tympanum remained consistently larger in area but thinner than the exposed side. Overall, these findings indicate that tympanal evolution reflects a balance of scaling constraints and configuration-specific associations with auditory pinnae.
