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

objectiveTo evaluate the clinical significance of WAI as a predictive marker for MD and LVAS among adults.

methodsParticipants included 110 ears with MD, 18 ears with LVAS, and 92 normal ears (control group) recruited from clinical audiology settings. The outcome measures included Wideband Energy Absorbance (WBA), Resonance Frequency (RF), admittance Magnitude (YM), and phase Angle (YA). Propensity Score Matching (PSM) was conducted to treat the group imbalance.

resultsCompared with the control group, The MD group exhibited significantly lower WBA between 1587 and 4000 Hz (p < 0.05), while the LVAS group showed lower WBA between 1000 and 2520 Hz (p < 0.05). The MD and LVAS groups had lower RF (p < 0.05), while they had higher YM at low frequencies (226 and 678 Hz for MD, and 1000 Hz for LVAS, p < 0.05).

conclusionsThis study showed that LVAS has a lower WBA at middle frequencies, whereas MD has a lower WBA at middle and high frequencies. These findings suggest that WAI may serve as a predictive marker for MD and LVAS. However, further studies are needed to explore its diagnostic utility in Third Mobile Window Abnormalities (TMWA). LEVEL OF EVIDENCE: IV: Retrospective cohort study.
