  "condition" text,
  "prothrombin_time" text,
  "partial_thromboplastin_time" text,

Question: In which condition(s) is bleeding time prolonged and prothrombin time unaffected?
SQL: SELECT "condition" FROM "laboratory_findings_in_various_platelet_" WHERE "bleeding_time"='Prolonged' AND "prothrombin_time"='Unaffected';

Question: How many entries for prothrombin time are there where platelet count is "decreased or unaffected"?
SQL: SELECT COUNT("prothrombin_time") FROM "laboratory_findings_in_various_platelet_" WHERE "platelet_count"='Decreased or unaffected';

Question: How is the bleeding time wherein platelet count is decreased and prothrombin time is unaffected?
SQL: SELECT "bleeding_time" FROM "laboratory_findings_in_various_platelet_" WHERE "platelet_count"='Decreased' AND "prothrombin_time"='Unaffected';

Question: What are all the possible bleeding time results where prothrombin time and platelet count are both unaffected?
SQL: SELECT "bleeding_time" FROM "laboratory_findings_in_various_platelet_" WHERE "prothrombin_time"='Unaffected' AND "platelet_count"='Unaffected';
