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

Anaemic retinopathy presents commonly with bilateral retinal haemorrhages and soft exudates. Unilateral optic disc oedema in these patients has rarely been mentioned. We report a case of an atypical presentation of anaemic retinopathy with recurrent unilateral optic disc oedema and retinal haemorrhages secondary to iron deficiency anaemia from a newly diagnosed colorectal adenocarcinoma.A man in his 70s with multiple ischaemic risk factors was referred for unilateral optic disc oedema associated with a few retinal haemorrhages. Initial diagnosis was that of impending central retinal vein occlusion. The optic disc oedema initially resolved but recurred 8 months later with worsening unilateral disc oedema, 'coin-shaped' retinal haemorrhages, Roth's spots and venous tortuosity. Full blood count showed microcytic hypochromic anaemia secondary to iron deficiency and colonoscopy revealed colorectal adenocarcinoma. The patient received blood transfusions, oral iron replacement and underwent surgical resection of the tumour. The anaemia resolved, and the fundus findings resolved as well.
