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

BACKGROUND AND

objectiveNitroglycerin, a cornerstone therapy for acute angina pectoris, achieves rapid symptom relief through sublingual administration by bypassing hepatic first-pass metabolism. This study aimed to investigate the pharmacokinetics (PK), bioequivalence, and safety profiles between a test (T) formulation and a reference (R) formulation of nitroglycerin sublingual tablets in healthy volunteers (HVs).

methodsIn this single-center, randomized, open, single-dose, two-part formulations, four-cycle, two-sequence complete repeat crossover design, fasting-dose bioequivalence study, HVs (n = 36) were 1:1 divided into two groups (T-R-T-R and R-T-R-T) and received 0.6 mg of nitroglycerin sublingual with a 3 d washout. Venous blood was collected 3 h after each administration. Plasma levels of nitroglycerin were analyzed using a high-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) technique, and PK parameters were calculated using noncompartmental methods.

resultsFor nitroglycerin, the bioequivalence between the test and reference formulations was assessed using the Reference-Scaled Average Bioequivalence (RSABE) method for the maximum plasma concentration (C

conclusionsThe study confirmed bioequivalence between the test and reference formulations, demonstrating equivalent absorption rates (C
