Natural history of progressive vision loss in Bietti crystalline dystrophy: a model-based meta-analysis.

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
purposeBietti crystalline corneoretinal dystrophy (BCD) is an autosomal recessive progressive retinal degenerative disease due to mutations in the
methodsBased on the individual data of untreated BCD patients, a disease progression model was established using the change in BCVA from baseline as an index, and covariates including age of onset, age, duration of disease, baseline BCVA, gender, race (East Asian/non-East Asian), genotype, and family history. Then, based on the final model, the natural disease progression characteristics of BCD were simulated.
resultA total of 14 studies met the inclusion criteria, with a total sample size of 117 cases, including 6 studies (N=80) with East Asian populations and 9 studies (N=37) with non-East Asian populations. The change of BCVA from baseline increased linearly with time, and the disease progression model of BCD was successfully established. BCVA increased by 0.06 logarithm of the minimum angle of resolution (LogMAR) per year in BCD patients. BCVA increased by 0.09 LogMAR per year in patients with BCVA≥0.5LogMAR and disease duration more than 10 years.
conclusionsFor the first time, we successfully established a BCD disease progression model based on the change in BCVA from baseline. The mean visual acuity loss increased linearly with the progression of the disease. A sharper loss of BCVA may be expected in patients with BCVA≥0.5LogMAR and disease duration ≥10 years.
