Micronutrient Deficiencies and Digital Computerized Phototrichogram Analysis in Telogen Effluvium: a Retrospective Correlation Study in a Tertiary Medical Center.

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
introductionTelogen effluvium (TE) is a common form of non-scarring alopecia that may manifest as acute or chronic hair shedding. Several studies evaluated a possible relationship between various vitamin and mineral deficiencies and TE, but it is still a controversial topic.
objectivesThis study aimed to investigate the status of vitamin and mineral deficiencies in patients diagnosed with TE and to evaluate their correlation with anagen hair ratios (AHR) calculated with an automated digital phototrichogram (ADCP).
methodsElectronic records of 973 TE patients were retrospectively analyzed. Demographic, clinical data, parameters such as ferritin, vitamin B12 (Vit-B12), vitamin D (Vit-D), folic acid, zinc and hemoglobin (HGB) serum levels were evaluated. Anagen to telogen hair ratios were also assessed in forty-two patients via ADCP.
resultsThe rates of anemia, low ferritin level, and Vit-B12, folate, Vit-D, and zinc deficiencies were 11.9% (N = 109), 44% (N = 332), 1.5% (N = 13), 2.5% (N = 14), 87% (N = 51), and 4.5% (N = 2), respectively. A positive correlation was found between HGB levels and AHR in female patients (Spearman rank, r = 0.417, P = 0.008). No statistically significant relationship was found between ferritin, Vit-B12, folate, zinc serum levels and AHR. The relationship between Vit-D and AHR could not be assessed due to the insufficient number of patients with Vit-D data.
conclusionsHGB value is the only marker that is positively correlated with the AHR of patients with TE. Ordering HGB can be used as an initial test for managing TE patients cost-effectively.
