Only first intravitreal bevacizumab injection achieves statistically significant visual improvement in naïve myopic choroidal neovascularization.

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
backgroundThe aim of this study was to evaluate the efficacy of intravitreal bevacizumab when administered on an as-needed basis for the treatment of myopic choroidal neovascularization (CNV), and to assess visual changes upon treatment.
methodsThis study was designed as a retrospective, interventional case series, for which the inclusion criteria were pathologic myopia, and documentation of untreated active macular CNV on fluorescein angiography and optical coherence tomography. Monthly changes in best-corrected visual acuity (BCVA), visual gain after each treatment, and correlation with refraction, age, location, and dimension of CNV were considered. The data were analyzed using the one-tailed, paired Wilcoxon test.
resultsNineteen naive eyes were found suitable for the study. The mean number of treatments was 3.32 ± 2.36 (confidence interval 2.25-4.37) during a mean follow-up period of 18.95 ± 8.3 months. At baseline, mean BCVA was 0.58 ± 0.37 logarithm of the minimum angle of resolution (logMAR) units. At 12 months, mean BCVA was 0.39 ± 0.35 logMAR and at 24 months was 0.39 ± 0.40. Mean improvement in BCVA from baseline was +0.17 ± 0.25 logMAR (P < 0.05) at month 12, +0.14 ± 0.25 logMAR (P = 0.1) at month 18, and +0.09 ± 0.32 logMAR (P = 0.5) at month 24. Improvement on pretreatment BCVA was significant (+0.16 logMAR, P < 0.01) after the first injection, but not after the second (-0.01 logMAR, P = 0.5) or third (+0.02 logMAR, P = 0.5) injections. There was a statistically significant correlation between age and number of treatments, and between improvement in BCVA of foveal versus extrafoveal location of CNV.
conclusionThe use of intravitreal bevacizumab "as needed" is an effective treatment for myopic CNV, but visual gain is statistically significant only after the first injection and decreases in the second year.
