Context: The tradition of birthday parties started in Europe a long time ago. It was feared that evil spirits were particularly attracted to people on their birthdays. To protect them from harm, friends and family members would come to stay with the birthday person and bring good thoughts and wishes. Giving gifts brought even more good cheer to keep away from the evil spirits. This is how birthday parties began. The following are some countries' birthday traditions: Canada---Putting butter on the nose. In Atlantic Canada, the birthday child's nose is put butter on for good luck. China---Noodles for lunch. The birthday child pays respect to his / her parents and receives a gift of money. Friends and relatives are invited to lunch and noodles are served to wish the birthday child a long life. England---Money cakes. Certain symbolic objects are mixed into the birthday cake as it is being prepared. If your piece of cake has a coin in it, you will be rich. Ireland---Birthday bump . The birthday child is lifted upside down and " bumped" on the floor for good luck. Italy---Pulling ears. The child's ears are pulled as many times as how old he / she is turning. Japan---New clothes. The birthday child wears new clothes to mark the occasion. New Zealand---Birthday claps. After the candles are hit, the happy birthday song is sung loudly and often out of tune and then the birthday person receives a clap for each year he / she has been alive and then one for good luck. The United States---Cake, candles and the birthday song. A cake is made, and candles are put on top based on how old the person is.

Context: To evaluate the effects of the sodium glucose cotransporter 2 (SGLT2) inhibitor empagliflozin added to metformin for 12weeks in patients with type 2 diabetes. This dose-ranging, double-blind, placebo-controlled trial randomized 495 participants with type 2 diabetes inadequately controlled on metformin [haemoglobin A1c (HbA1c) >7 to 10%] to receive 1, 5, 10, 25, or 50mg empagliflozin once daily (QD), or placebo, or open-label sitagliptin (100mg QD), added to metformin for 12weeks. The primary endpoint was change in HbA1c from baseline to week 12 (empagliflozin groups versus placebo). Reductions in HbA1c of -0.09 to -0.56% were observed with empagliflozin after 12weeks, versus an increase of 0.15% with placebo (baseline: 7.8-8.1%). Compared with placebo, empagliflozin doses from 5 to 50mg resulted in reductions in fasting plasma glucose (-2 to -28mg/dl vs. 5mg/dl with placebo; p<0.0001) and body weight (-2.3 to -2.9kg vs. -1.2kg; p<0.01). Frequency of adverse events was generally similar with empagliflozin (29.6-48.6%), placebo (36.6%) and sitagliptin (35.2%). Hypoglycaemia rates were very low and balanced among groups. Most frequent adverse events with empagliflozin were urinary tract infections (4.0% vs. 2.8% with placebo) and pollakiuria (2.5% vs. 1.4% with placebo). Genital infections were reported only with empagliflozin (4.0%). Once daily empagliflozin as add-on therapy to metformin was well tolerated except for increased genital infections and resulted in reductions in HbA1c, fasting plasma glucose and body weight in patients with type 2 diabetes inadequately controlled on metformin monotherapy. 
 Question: Which protein does empagliflozin inhibit?
