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
backgroundPhysical exercise has been proposed as a feasible strategy for preventing and managing glaucoma by modulating intraocular pressure (IOP) and ocular perfusion pressure (OPP). The primary objective of this cross-sectional study was to assess the IOP and OPP responses to dynamic resistance exercises (leg extension and biceps curl).
methodsTwenty-six patients with primary open-angle glaucoma (POAG) (age = 68.9 ± 8.1 years) and 18 healthy age-matched controls (age = 69.6 ± 5.9 years) were recruited. Participants performed one set of 10 repetitions of both exercises at low- (light bar) and moderate-intensity (15RM). IOP and blood pressure were measured at baseline and after 1 and 5 min of passive recovery. Additionally, IOP was measured during training after each of the 10 repetitions.
resultsOur data showed a progressive IOP increase throughout the sets of leg extension and biceps curl exercises when performed at moderate intensity (p < 0.001). Remarkably, POAG patients showed a smaller IOP increase compared to controls (p = 0.048). The between-group differences for IOP changes were higher during the 10 exercise repetitions at moderate-intensity for both leg extension (average IOP rise: POAG = 0.3 ± 0.6 mmHg vs. control = 2.3 ± 0.7 mmHg) and biceps curl (average IOP rise: POAG = 1.4 ± 0.6 mmHg vs. control = 3.4 ± 0.8 mmHg) exercises. No changes in OPP were observed.
conclusionsThe findings of this study suggest that moderate-intensity dynamic resistance training is a safe intervention for potentially improving physical fitness in medically treated POAG patients.
