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

Mucosa-associated lymphoid tissue, which plays a crucial role in both immunological protection and inflammation at mucosal sites, shows interspecies variation in its distribution. In the ocular region, lacrimal duct-associated lymphoid tissue (LDALT) has rarely been investigated in animals other than humans or rodents. Although conjunctiva-associated lymphoid tissue (CALT) has been reported in various species, its cell composition remains unclear. Herein, we aimed to elucidate the morphology and development of the feline ocular immune system by examining the lacrimal tract and its associated tissues in adolescent (7- to 8-month-old) and fetal cats. The feline lacrimal tract, composed of the lacrimal canaliculi, lacrimal sac, and nasolacrimal duct, was visualized using CT. Histologically, a small lymphocyte aggregate, identified as LDALT, was observed exclusively along the lacrimal canaliculus in one of the four adolescent cats. In contrast, extensive development of the CALT was observed in tissues surrounding the openings of the lacrimal tract, particularly on the cornea-facing side of the third eyelid. CALT is characterized by CD20
