Anterior chamber morphology changes in eyes with narrow angles by Scheimpflug imaging: Pilocarpine versus laser peripheral iridotomy.
Trial report in International ophthalmology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. 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
purposeTo evaluate morphometric variables, like anterior chamber angle (ACA), anterior chamber volume (ACV) and central anterior chamber depth (CACD) after pilocarpine administration and after prophylactic laser peripheral iridotomy (LPI) in eyes with primary angle-closure disease (PACD).
designProspective cohort study
methodsNinety-one eyes of 91 patients with narrow angles were consecutively enrolled in this prospective interventional study. All patients were classified into primary angle-closure suspect (PACS), primary angle-closure (PAC) and primary angle-closure glaucoma (PACG). If both eyes were eligible, one eye was randomly selected for study inclusion. ACV, ACD and ACA were evaluated using Scheimpflug imaging technology at three time points: at baseline (T0), 45 min after application of pilocarpine before LPI (T1) and at one-month post-LPI (T2).
resultsPACS, PAC and PACG groups included 25 (27.4%), 24 (26.3%) and 42 (46.1%) eyes, respectively. At both time points T1 and T2, mean pupil diameter, ACV and ACA changed significantly (P = 0.00). In all subgroups, ACD decreased significantly at T1 and then increased significantly at T2. ACA was widened by 6 degrees in angles < 26 degrees as compared to 3 degrees in > 26 degrees eyes. In PACG group, mean ACV increased significantly between T0 and T2 (P = 0.0). Other parameters like mean cornea volume (P = 0.27), central corneal thickness (P = 0.29) showed no significant change between time points (T0, T1 and T2). Pilocarpine instillation caused a significant increase in ACA, ACV and ACD
conclusionScheimpflug imaging detected significant changes in ACD post-LPI and post-pilocarpine in all groups. However, ACV changed significantly only in PACS and PACG.
