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

Poly (lactic-co-glycolic acid) (PLGA) has been used in many long-acting drug formulations which have been approved by the US Food and Drug Administration (FDA). However, generic counterparts for PLGA products have yet to gain FDA approval due to many complexities in formulation, characterization, and evaluation of test products. To address the challenges of generic development of PLGA-based products, the FDA has established an extensive research program to investigate novel methods and tools to aid both product development and regulatory review. The research focus have been: (1) analytical tools for characterization of PLGA polymers; (2) impacts of PLGA characteristics and manufacturing conditions on product performance; (3) in vitro drug release testing and in vitro-in vivo correlation of PLGA-based products, and (4) modeling tools to facilitate formulation design and bioequivalence study design of PLGA-based drugs. This article provides an overview of FDA's PLGA research program and highlights scientific accomplishments as well as regulatory outcomes that have resulted from successful research investigations.
