Multiple micronutrient deficiencies as a long-term complication of bariatric surgery.
Article in BMJ case reports, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 2 of them syntheses that pooled 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.
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
Micronutrient deficiencies may develop as a long-term complication of bariatric surgery due to alteration of gut anatomy and disruption of normal gut absorption. Inadequate repletion of essential vitamin and mineral deficiencies can lead to multisystem dysfunction. We present a case of a woman in her 50s, with a history of Roux-en-Y gastric bypass over 10 years ago, who presented with generalised weakness and a diffuse desquamating rash. A punch biopsy performed was compatible with nutritional deficiency. Labs revealed low levels of micronutrients A, B
