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
Sudden Sensorineural Hearing Loss (SSNHL) is a distressing condition with limited treatment options. This prospective study aimed to investigate the effectiveness of intratympanic Platelet Rich Plasma (PRP) as a salvage treatment for SSNHL. 56 consecutive patients with unilateral SSNHL, unresponsive to conventional treatments, were administered two intratympanic injections of autologous PRP 10 days apart and hearing threshold evaluated after one month. Audiometric data before and after PRP injections revealed a significant mean hearing gain of 11.99 dB which was more in lower frequencies (250, 500, 1000 Hz) reaching upto 13.88dB. Notably, improvement was observed in patients with amino glycoside-induced hearing loss, even after prolonged symptom duration. Additionally, 8 out of 17 patients reported subjective improvement in tinnitus. No serious adverse events were noted, and patients tolerated the procedure well. Intratympanic PRP holds promise as a salvage treatment for SSNHL, particularly in cases where conventional treatments have failed. Further research with larger sample sizes and comparative studies is warranted to establish PRP's role as a primary therapy for SSNHL and explore its long-term benefits. Its role in treatment of tinnitus also needs to be explored.
