Echocardiographic evaluation of Takayasu arteritis including speckled tracking echocardiography and aortic stiffness.
Article in Indian heart journal. 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
introductionDespite the burden of Takayasu's arteritis (TA) in India, data on LA, LV and RV strain and aortic stiffness is scanty.
aimsWe assessed these in 100 TA patients (mean age 29.8 years, 70 % females) and correlated with disease activity and duration. METHODS AND
resultsMean illness duration was 6.34 years, Numano V and III angiographic type was seen in 42 and 20 %. Global LVEF was normal and 6 % had LVEF <50 %. TA patients had significantly lower LVGLS (-16.09 vs -18.9 %), peak atrial longitudinal strain (PALS: 25.03vs 27.1 %), RV-FWS (23.42 vs 25.2 %), and higher mean aortic stiffness (8.39 vs 7.44 m/s) vs controls. The % of patients with LV GLS > -16 %, PALS < -25 %, RV-FWS > -23 % and aortic stiffness (>12 m/s) was 32, 26, 14 and 17 % respectively. Those with LVGLS > -16 % had longer symptom duration (7.02 vs 5.66 years), higher ITAS score (4.96 vs 4.44), higher % prevalence of impaired RV strain (28 % vs 7 %) and impaired PALS (29 % vs 18 %). Those with abnormal aortic stiffness had higher mean ITAS scores (5.58 vs 3.62), higher chance of active disease (ITAS-2010 ≥ 2, 64 % vs 40 %) and longer disease duration.
conclusionDespite normal global LVEF, 15-32 % patients with TA had impaired LVGLS, RVFWS, PALS and aortic stiffness. Impaired LVGLS and Aortic stiffness correlated with longer disease duration and higher disease activity. These preliminary findings suggest that strain and aortic stiffness evaluation in TA may help in early identification of subclinical ventricular dysfunction.
