The Choice of Drainage Device in Complicated Glaucomas: Comparing Ahmed and Baerveldt Implants.
Article in In vivo (Athens, Greece). The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 4 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
BACKGROUND/
aimGlaucoma is a chronic and progressive optic neuropathy which leads to deterioration of visual function. It is estimated to be the second leading cause of severe vision loss and blindness worldwide. Failure of anti-glaucoma medication to sufficiently reduce intraocular pressure (IOP) and poor compliance with medication are indications for glaucoma surgery, for example using glaucoma drainage devices. Our aim was to compare the surgical outcomes following the implantation of Ahmed FP7 and Baerveldt 350 drainage devices. PATIENTS AND
methodsFive hundred and fifty-two patients with primary or secondary glaucoma were enrolled in the study. All patients had a history of failed trabeculectomy or other intraocular surgery, and IOP ≥18 mm Hg. The implantation of Ahmed (266 patients) or Baerveldt (286 patients) devices was randomly performed in the patients, who were subsequently examined for a period of 5 years. Follow-up visits were scheduled 1 day; 1 week; 1, 3 and 6 months; and 1, 1.5, 2, 3, 4 and 5 years postoperatively.
resultsSignificant reduction of IOP was achieved in both groups. Ahmed valve (28.3±9.3, 13.4±6.9, 14.2±6 and 12.7±4.5 mmHg at baseline, 1, 3, and 5 years postoperatively, respectively) resulted in significantly greater IOP reduction compared to Baerveldt implant (29.6±10.1, 15.4±5.5, 14.5±5.5 and 14.7±4.4 mmHg at baseline, 1, 3, and 5 years postoperatively, respectively). A significantly lower number of medications was required in the Ahmed group in comparison to the Baerveldt one (Ahmed group: 1.5±1.4, 1.4±1.5 and 1.8±1.5; Baerveldt group: 1.9±1.3, 1.9±1.3 and 2.2±1.4, respectively). The incidence of treatment failure and the rate of glaucoma reoperation were significantly higher in the Baerveldt group (40%) compared to the Ahmed group (17%).
conclusionAhmed drainage implantation seemed to outclass that using the Baerveldt device in our study, in terms of efficacy and success rate.
