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

Purpose: This study aimed to develop, characterize, and clinically evaluate a novel 6% nitroglycerin (NTG) Aloe vera gel formulation as a transdermal alternative to conventional sublingual NTG therapy in patients with stable angina pectoris. Patients and Methods: A randomized, parallel-group, double-blind clinical trial was conducted involving 150 patients with stable angina, allocated to receive either 6% NTG-Aloe vera gel or standard sublingual NTG tablets (0.6mg). The gel was assessed for physicochemical parameters, FTIR compatibility, stability under ICH guidelines, and in vitro drug release kinetics. Dermatological safety was evaluated via skin irritation testing. Clinical efficacy was determined by Numeric Pain Rating Scale (NPRS), chest tightness scores, Seattle Angina Questionnaire (SAQ), and vital parameters, including blood pressure and oxygen saturation. Results: The NTG Aloe vera gel demonstrated desirable physicochemical properties, sustained zero-order drug release, and excellent stability with no significant degradation. Clinical data revealed that the gel provided gradual, sustained pain and chest tightness relief, superior SAQ scores (p<0.001), and improved tolerability compared to sublingual NTG. Importantly, the gel induced a controlled hypotensive response without abrupt cardiovascular changes, indicating enhanced safety. No dermatological adverse effects were reported. Conclusion: This pilot study showed 6% NTG-Aloe vera gel offers a stable, effective, and patient-friendly transdermal delivery system for angina management, meriting further large-scale and long-term evaluations. Registration: Clinical Trial Registry-India (CTRI/2024/11/076947).
