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
The incidence of otosclerosis is lower in yellow and black populations compared to white populations. Preoperative diagnosis and surgical indications are based on clinical features and audiological evaluations. To summarize the clinical features and analyze audiological characteristics of otosclerosis in China, aiming to improve the diagnosis and determination of surgery given its low incidence in the country. A retrospective analysis was conducted involving 80 ears (48 patients) who underwent surgery for otosclerosis from 2003 to 2023. Among the patients, 88.8% experienced tinnitus, only 2.5% had Willis paracusis, Schwarz sign was all absent, and Gellé test was negative in 98.7%. Furthermore, 31.2% of the patients did not exhibit a Carhart notch, while 63.6% had a Carhart notch at 2 kHz, and 5.2% at 1 kHz. Tinnitus is the main accompanying symptom of otosclerosis. Willis Paracusis and Schwarz sign are relatively rare in otosclerosis. The Gellé test provides reliable diagnostic criteria for otosclerosis. The presence of a Carhart notch is not definitive for diagnosing otosclerosis and does not appear exclusively at 2 kHz. Significance: P < 0.05.
