Effects of Insulin-Like Growth Factor (IGF-1) in Patients with Sensorineural Hearing Loss.
Trial report in The journal of international advanced otology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers.
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
objectives(1) To test the effect of local administration of insulin-like growth factor-1 (IGF-1) in patients with sensorineural hearing loss (SNHL). (2) To test the effect of local administration of IGF-1 in patients with ototoxicity.
methodsForty patients with SNHL were included in the study. Their hearing thresholds at different frequencies (0.5, 1, 2, and 4 kHz) along with the average hearing threshold were noted. The patients were then randomly allocated to 2 groups and were treated with IGF-1 via one of the following routes: (1) intratympanic injection and (2) Gelfoam. Patients were followed-up at weekly intervals for 6 weeks but follow-up PTA was done at 3 weeks, 6 weeks, and 6 months only.
resultsForty patients (25 male, 15 female) participated in the study. Their age ranged from 13 to 63 years, with a mean of 31.3 years. Nineteen (47.5%) patients exhibited some degree of recovery after 6 months of follow-up, while 21 (52.5%) did not exhibit any recovery. Fourteen (35%) patients showed slight recovery (SR), 1 (4%) patient showed marked recovery, and complete recovery was observed in 4 (10%) patients. Twelve of the 20 patients who underwent treatment using Gelfoam showed improvement in hearing (measured as a reduction in hearing threshold), while only 7 of the 20 patients who underwent intratympanic injection showed such improvement. Among adverse reactions, the most common was pain (88%) which typically did not last beyond 3 days. Other adverse reactions observed were dizziness (24%) and headache (20%). One patient suffered from acute suppurative otitis media (ASOM) and had a perforation in the tympanic membrane. However, this was treated successfully with medications.
conclusionIntratympanic IGF-1 is a novel drug that has shown early promise in controlling and reversing SNHL.
