Comparison of Two Tube-Modification Techniques in Baerveldt Glaucoma Implantation in Refractory Glaucoma.

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
importanceTo compare treatment outcomes among a stent group, ligature group and combined group in eyes with refractory glaucoma.
backgroundVarious techniques have been used intra-operatively to restrict the aqueous flow in Baerveldt glaucoma implantation.
designRetrospective chart review.
participantsAll glaucoma patients aged over 18-years old who had Baerveldt implantation in Ramathibodi Hospital, Bangkok, Thailand, between October 2011 and February 2018 were included for analysis.
methodsRetrospective interventional research was conducted. All glaucoma patients who underwent drainage device implantations were retrospectively reviewed from medical records and divided into three groups: stent group, ligature group, and combined group. The primary outcome was post-operative intraocular pressure (IOP) changes and BCVA (logMAR) change. The secondary outcome is treatment failure. Repeated measurements with mixed models and multi-level parametric survival model stratified by propensity score and eye side were used to compare the primary and secondary outcomes between stent group and ligature group.
main outcome measuresTreatment failure between two groups.
resultsA total of 163 patients with a mean age of 57.11 ± 19.04 years, implanted with Baerveldt tube, were eligible. There were no significant differences between stent and ligature groups in terms of post-operative IOP changes [mean difference with 95% confidence interval = 0.53 (-0.49, +1.55) vs -0.02 (-0.84, +0.81); P = 0.411] and post-operative BCVA (logMAR) change (0.02 (-0.13, +0.18) vs -0.05 (-0.18, +0.07); P = 0.465). The hazard ratio and 95% confidence interval of treatment failure in ligature group were 2.57 (0.72-9.19) compared with the stent group.
conclusionThis study suggests a trend toward a better result in the stent group compared with the ligature group. Further research with a larger sample size and randomized control trial is warranted.
