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 demonstrate longitudinal structural and functional changes and predictors in patients with acute primary angle-closure (APAC) attack compared to non-acute primary angle-closure glaucoma (PACG) treated with laser peripheral iridotomy (LPI).
methodsIntraocular pressure (IOP) was assessed quarterly in this retrospective and longitudinal study, with IOP fluctuation calculated. Retinal nerve fiber layer (RNFL) thickness, mean deviation (MD), and visual field index (VFI) were assessed biannually using optical coherence tomography (OCT) and VF testing. IOP in supine and lateral decubitus positions (LDP) were measured using rebound tonometry (Icare Pro). Anterior segment structures were assessed using anterior segment OCT. Linear mixed models analyzed MD and VFI changes and their predictors.
resultsAPAC (40 eyes) exhibited long-term RNFL thinning and VF deterioration comparable to non-acute PACG (40 eyes). APAC had greater IOP elevation at LDP (5.2 vs. 2.4 mmHg, P < 0.001) and long-term IOP fluctuation (8.6 vs. 7.1 mmHg, P = 0.048). Multivariable analysis revealed that greater LDP IOP elevation (β=-0.06, P = 0.001) and peripheral anterior synechiae (PAS) (β=-0.37, P = 0.007) were predictive of MD decline in APAC. Female (β=-0.30, P = 0.023), higher LV (β=-1.17, P = 0.002), greater IOP fluctuation (β=-6.40, P < 0.001), and worse baseline VFI (β=-0.01, P < 0.001) predicted VFI deterioration in PACG. Greater LV (β = 0.09, P = 0.006), smaller angle opening distance (β=-0.27, P = 0.002), trabecular iris space area (β=-0.60, P = 0.003), and scleral spur angle (β=-0.002, P = 0.007) were associated with greater IOP fluctuation in PACG.
conclusionIn APAC, greater LDP IOP elevation and PAS may be early indicators for progression, while baseline greater LV and long-term IOP fluctuation predicted visual deterioration in non-acute PACG.
