1 · What the graph read from 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.

2 · The registry

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 radiographic lacrimal gland (LG) volume and dimensions in Ahmed glaucoma valve (AGV)- versus trabeculectomy-treated eyes and contralateral non-treated eyes.

methodsIn this retrospective cohort study, 1616 medical records acquired between 2010 and 2020 were examined. In AGV-treated (group 1) eyes, there were 19 patients with records sufficient for radiological LG evaluation, and in trabeculectomy-treated (group 2) eyes, there were 18. The hospital workstation software was used to assess high-resolution computed tomography (HRCT) scans conducted under standard protocol using a 128 SL Optima CT 660 scanner. The software (Vitrea™) was used to perform semi-quantitative volumetric measurements. LG dimensions were obtained in the axial and reformatted coronal planes on each side, and four measures were generated using the widest LG tip-to-tip diameters in two planes: coronal length, coronal width (CW), axial length (AL), and axial width.

resultsThe time interval between surgery and HRCT imaging was 50.97 ± 26.25 months. Group 1 had significantly lower LG volume than group 2 (594.11 ± 259.45 vs. 933.67 ± 294.09 mm

conclusionsAGV and trabeculectomy had varied impacts on LG volume and dimensions despite being conducted in the same quadrant. HRCT appears to be effective in analysing AGV position, which may be related to LG volumetric and dimensional issues.
