Can Tiger (TIG) Catheters Be a Solution to the Radial Artery Spasm (RAS) in Coronary Angioplasty? A Case-Based Report of Successful Reperfusion With the Use of 5-French (Fr) TIG Catheter and Literature Review.
Article in Cureus, 2022. 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
Conventionally, during a primary percutaneous coronary intervention (PPCI), a diagnostic catheter is used to visualize the contralateral coronary system from the site of the acute occlusion. For that purpose, Judkins Right 4 (JR4) or Judkins Left 3.5 (JL3.5) diagnostic catheters are usually preferred, depending on the ECG findings. On the other hand, the use of a dedicated diagnostic catheter in the setting of PPCI is supported only by evidence extrapolated from coronary angiography on patients with stable coronary artery disease. We present a case of a 46-year-old patient who presented with ST-segment elevation myocardial infarction (STEMI) and underwent successful PPCI. A 6-French (Fr) radial sheath was placed in the right radial artery. Due to the presence of ST-segment elevation in both the inferior as well as in the anterior precordial leads, raising the possibility of a wrap-around left anterior descending (LAD) artery as the infarct-related artery, a 5-Fr Tiger (TIG) diagnostic catheter was initially used for cannulation of the left coronary system. The culprit lesion was identified in the proximal part of a small second right ventricular (RV) branch where it was 100% occluded with thrombus and the patient had a successful PPCI.
