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
purposeDyslipidemia has been implicated in the pathogenesis and prognosis of sudden sensorineural hearing loss (SSNHL). Remnant cholesterol (RC), a novel lipid parameter, predicts cardiovascular outcomes independently of traditional lipid indices, but its prognostic value in SSNHL remains unclear. We examined whether baseline RC is associated with short-term hearing outcome after systemic treatment.
methodsWe conducted a retrospective cohort study of 399 patients diagnosed with SSNHL who received standardized systemic treatment for 1-2 weeks. RC was calculated as total cholesterol - LDL-C - HDL-C. The primary endpoint was non-recovery, defined as a pure-tone average (PTA) improvement < 15 dB; sensitivity analyses used < 10 dB based on different guidelines. Multivariable logistic regression and restricted cubic spline analyses were used to evaluate associations. Patients were additionally stratified by LDL-C and RC to assess prognostic information beyond LDL-C.
resultsOf the 399 patients, 178 (44.6%) achieved short-term hearing recovery. Higher RC was independently associated with non-recovery (adjusted OR 2.25, 95% CI 1.34-3.77; P = 0.002), and spline analyses suggested an approximately linear relationship. Findings were consistent using the 10 dB definition (adjusted OR 2.10, 95% CI 1.31-3.36; P = 0.002). Compared with low LDL-C/low RC, non-recovery odds were higher in high LDL-C/low RC (adjusted OR 1.85, 95% CI 1.17-2.95), low LDL-C/high RC (adjusted OR 3.52, 95% CI 1.37-9.06), and high LDL-C/high RC (adjusted OR 2.06, 95% CI 1.63-4.41).
conclusionsElevated RC is independently associated with poorer short-term recovery in SSNHL. RC may serve as an easily obtainable biomarker for short-term recovery stratification in SSNHL.
