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

Introduction: Turkish permits grammatical non-canonical word order while morphological case marking disambiguates thematic roles. Methods: We examined comprehension accuracy and verb-locked event-related potentials (ERPs) to Turkish canonical subject-object-verb (SOV) and non-canonical object-subject-verb (OSV) sentences in adults ( Results: Accuracy was lower for OSV than SOV in both groups, with a significantly larger SOV-OSV accuracy difference in children. Adults showed a late posterior OSV > SOV positivity, with significant effects in several prespecified windows within the 600-1,200-ms interval, consistent with increased sentence-final processing demands associated with the non-canonical configuration at the final verb. Children showed no reliable corresponding positivity after correction for multiple comparisons. Critically, however, Group × Sentence Type interactions did not survive correction, providing insufficient evidence that the magnitude of the SOV-OSV ERP effect differed between adults and children. Within children, chronological age showed no reliable linear or quadratic association with the behavioral or ERP SOV-OSV difference across the sampled age range. By contrast, stronger grammatical ability predicted higher comprehension accuracy in both sentence types beyond age; the same general pattern was obtained for broader language ability. Neither grammatical nor broader language ability reliably modulated the SOV-OSV ERP difference. Discussion: Overall, the findings suggest that the availability of morphosyntactic case cues does not by itself entail adult-like efficiency in integrating those cues during sentence comprehension, and that developmental patterns may be expressed differently across behavioral and electrophysiological measures.
