Small-incision phacotrabeculectomy versus phacoemulsification in refractory acute primary angle closure with cataract.
Trial report in BMC ophthalmology, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 11 papers, 1 of them a synthesis that pooled it.
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
backgroundAcute primary angle closure (PAC) can be refractory to conventional treatment and intraocular pressure (IOP) is beyond control. Surgical intervention should be considered at the moment. The aim of the study was to compare small-incision phacotrabeculectomy (phacotrab, small-incision trabeculectomy combined with phacoemulsification) with phacoemulsification (phaco) in patients with refractory acute PAC and coexisting cataract.
methodsAnalyzed 49 eyes (49 patients) with acute PAC and cataract received small-incision phacotrab (24 eyes) or phaco (25 eyes) randomly. All these cases were refractory to conventional treatment involved the use of preoperative topical IOP-lowering agents, corticosteroids, mannitol, methazolamide and paracentesis to reduce IOP. The effects on best corrected visual acuity (BCVA), IOP, anterior chamber depth (ACD), glaucoma medications, and complications were observed for twelve months.
resultsAfter operation BCVA of 18 patients (75 %) in phacotrab group and 20 patients (80 %) in phaco group improved compared to preoperative vision. No statistically significant differences in mean BCVA were found between the two groups. The mean postoperative IOP levels at all follow up time points were lower than the mean preoperative IOP in each group (P < 0.001). There was statistically significant difference in mean IOP between the two groups only at 12 months postoperatively (P = 0.006). The surgical success rate (without medications, IOP ≤ 21 mmHg) was 83.33 % (20 eyes) and 72 % (18 eyes) in phacotrab group and phaco group respectively at 12 months. No statistically significant differences in the mean ACD were found between the two groups. There were no serious intra- or post-operative complications in the two treatment groups.
conclusionsBesides phaco, small incision phacotrab may be another effective and safe choice in the treatment of patients with refractory acute PAC and coexisting cataract. Whether phacotrab is more effective in IOP control in the long term needs to be verified in the further.
