Gastrointestinal pathology in patients presenting with iron deficiency anaemia: A single-centre cross-sectional study.
Article in Journal of family medicine and primary care, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: About a third of the world's population is estimated to suffer from anaemia, and iron deficiency is expected to account for about half of all anaemia cases. This study was designed to get an estimate of the proportion of patients with iron deficiency anaemia (IDA) who have a significant gastrointestinal (GI) pathology, in particular a GI malignancy, and to identify any risk factors or predictors for the same. Methods: This cross-sectional study was conducted at a hospital in Eastern India. The study population comprised males above the age of 18 and postmenopausal females with IDA, excluding those haemodynamically unstable or with chronic diseases. Data collection included a detailed history, sociodemographic details, dietary habits, GI symptoms, and severity of anaemia. Faecal occult blood tests (OBTs) were conducted, and patients were referred for upper and lower GI endoscopy with biopsies. Results: Out of the 257 patients, 50.97% (n = 131) had a significant GI pathology, and 25.68% (n = 66) had a GI malignancy. Male gender (AOR: 5.203, 95% CI: 1.725-15.698) and a positive stool OBT (AOR: 6.516, 95% CI: 2.255-18.828) were found to be independent risk factors for any GI pathology. Age 40 years or above (AOR: 11.376, 95% CI: 1.199-107.946), loss of appetite (AOR: 15.548, 95% CI: 1.416-170.735), pain abdomen (AOR: 5.566, 95% CI: 1.149-26.953), dysphagia (AOR: 7.945, 95% CI: 1.036-60.915), family history of malignancy (AOR: 46.726, 95% CI: 4.076-535.645), and positive OBT (AOR: 22.430, 95% CI: 3.933-127.915) were found to be independent risk factors of GI malignancy. Conclusions: This study shows that a large proportion of adult males and postmenopausal females presenting with IDA in India have significant GI pathology. Furthermore, a significant proportion of them have GI malignancies. Thus, bidirectional endoscopy should be considered for these patients. Male patients, age >40, those with history of loss of appetite or weight, pain abdomen or dysphagia, positive family history, and positive OBT should be prioritised for the investigation.
