Factors affecting the early and mid-term success of needling for early failure of filtering bleb.
Article in Indian journal of ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Purpose: The purpose of this study is to evaluate the factors affecting the success of needling surgery for early filtering bleb failure after trabeculectomy. Methods: Patients who underwent a single needling surgery within 3 months after trabeculectomy were retrospectively evaluated. Glaucoma type, intraocular pressure (IOP), and medical treatments before trabeculectomy; the presence of hypotony after trabeculectomy; bleb type; IOP before needling; lens status; complications; IOP after 1, 6, and 12 months; and medical treatments after needling were recorded. Risk factors were evaluated for complete success at 1, 6, and 12 months after needling. Results: Thirty-three eyes of 33 patients were analyzed. The mean IOP after needling at 1, 6, and 12 months was 16.09 ± 3.70, 15.64 ± 2.68, and 15.79 ± 2.61 mmHg, respectively. The mean age of the patients was 53.97 (25-79) years. The mean IOP after needling at 1, 6, and 12 months was 16.09 ± 3.70, 15.64 ± 2.68, and 15.79 ± 2.61 mmHg, respectively. The pre-needling IOP and IOP decrease on the first day affected the complete and qualified success at 1, 6, and 12 months, but the glaucoma type, presence of hypotony after trabeculectomy, lens status, interval between trabeculectomy and needling, and bleb type were not found to affect success. In the receiver operating curve analysis, the pre-needling IOP value was found to be significant in determining complete success. Complete success at 1 month was more likely when the pre-needling IOP cutoff value was <24.5 mmHg. Conclusion: According to the results of single needling surgery performed within 3 months after trabeculectomy, the pre-needling IOP and IOP decrease with needling were found to be factors affecting success. Regardless of the time between the primary trabeculectomy and needling, effective needling will be successful before the IOP rises to high levels. Keeping the IOP at low values with medical treatment until the needling process is performed will have a positive effect on success.
