Validity of Skin Prick Test to Bermuda Grass in a desert environment.

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 AND
aimSkin prick test (SPT) with a wheal diameter of >3 mm, generally accepted as a positive, is most commonly use diagnostic tool for Allergic rhinitis. Aim was to validate wheal size of Skin Prick Test for the Bermuda grass, in desert environment, with positive Bermuda grass Nasal challenge in same environment.
methodsIn 53 adults, mean age 33.43 ± 9.36 years, both gender (females: 33.96%), SPT positive on Bermuda grass with cut off wheal longest diameter of 3 mm, Bermuda grass nasal challenge test (bgNCT) was carried out. Response was assessed subjectively (scored) and objectively (PNIF). Safety profile was assessed by PEF measurement.
resultsMean weal size of SPT (mm) was bigger in bgNCT positive patients (n=47; 88.68%) 8 [4, 15] vs 5 [3, 6] (p<0.0001). ROC analysis showed Bermuda Grass SPT at the threshold of >6.5mm enabled identification of Bermuda challenge with sensitivity of 82.98% and specificity of 100.0% (area under the curve 0.9326, standard error 0.03528; 95% confidence interval (CI): 0.8635 to 1.002; p=0.0006203).
conclusionsA SPT wheal size ≥6.5mm might be considered as an appropriate wheal size for confirming Bermuda grass allergy in adults with SAR, avoiding the demanding, time consuming and often unavailable bgNCT, especially in patients eligible for allergen immunotherapy. In these patients, bgNCT is recommended if SPT wheal size is <6.5 mm.
