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

purposeTo evaluate the expression of betaB(2)-crystallin mRNA and protein in rat, bovine, and human nonlens and nonocular tissues.

methodsbetaB(2)-crystallin mRNA levels were detected by RT-PCR. betaB(2)-crystallin protein was purified from rat and bovine tissues by FPLC chromatography. FPLC fractions were analyzed by immunoblotting. The identity of betaB(2)-crystallin protein, isolated from the retina, was confirmed by protein microsequencing.

resultsbetaB(2)-crystallin transcript was detected in rat brain, rat testis, and human retina by RT-PCR. betaB(2)-crystallin transcript was not found in rat lung, heart, ovary, spleen, thymus, kidney, and liver or in human brain and testis. betaB(2)-crystallin protein was partially purified from and its identity confirmed in rat brain, rat testis, and bovine retina. The bovine retinal protein was further confirmed to be authentic betaB(2)-crystallin by protein microsequencing.

conclusionsThese results establish that betaB(2)-crystallin mRNA and protein are expressed in tissues outside of the lens and outside of the eye including retina, brain, and testis. Extralenticular and extraocular expression of betaB(2)-crystallin, coupled with its participation in phosphorylation pathways, suggests that it has nonrefractive functions in these tissues.
