Assessment of the effects of direct/video-observed therapy on pulmonary function test parameters and asthma control test: A single-center prospective randomized pilot study.

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
Background & Objective: Asthma control depends largely on adherence to inhaled controller therapy and correct inhaler technique, yet both remain suboptimal in routine practice. Telemedicine-based monitoring has emerged as a feasible strategy to support patient education and adherence. This pilot study aimed to evaluate the feasibility and potential effects of video-observed therapy (VOT) on pulmonary function test parameters and Asthma Control Test (ACT) scores in adults with asthma. Methodology: This single-center, randomized prospective pilot study was conducted between January 2024 and August 2024 at Giresun Dr. Ali Menekşe Chest Diseases Hospital on asthma patients who were not in an exacerbation phase. Participants were allocated to either a video-observed therapy (VOT) group or a control group using simple randomization. Patients in the VOT group received baseline inhaler training and were followed via brief (~3-minute) video calls on days 15 and 30. All patients were reassessed in person at day 45 with spirometry and ACT. Results: Eighty-eight patients were analyzed (VOT, n = 25; control, n = 63). At baseline, the VOT group had a lower ACT score than the control group (14.9 ± 1.9 vs 17.5 ± 3.7; Conclusion: This pilot study suggests that brief, structured video-observed therapy is feasible in routine outpatient asthma care and may support modest improvements in spirometric and patient-reported outcomes. However, adjusted analyses did not confirm an independent treatment effect, and these findings should be regarded as hypothesis-generating. Larger, multicenter randomized trials with balanced allocation, longer follow-up, and objective adherence and inhaler-technique measures are needed before video-observed therapy can be recommended for routine asthma management.
