Your goal is to extract structured information from the user's input that matches the form described below. When extracting information please make sure it matches the type information exactly. Do not add any attributes that do not appear in the schema shown below.

```TypeScript

 { // Information on the clinical trial characteristics from the abstract
 conditions: string // The condition or disease being treated in the clinical trial

Please output the extracted information in JSON format. Do not output anything except for the extracted information. Do not add any clarifying information. Do not add any fields that are not in the schema. If the text contains attributes that do not appear in the schema, please ignore them. All output must be in JSON format and follow the schema specified above. Wrap the JSON in <json> tags.



Input:Lidocaine jelly and plain aqueous gel for urethral straight catheterization and the Q-tip test: a randomized controlled trial.  To compare the pain perception between lidocaine and plain aqueous gel during assessment of postvoid residual volume and the Q-tip test. : Patients were randomly assigned to either to 2% lidocaine hydrochloride jelly or plain aqueous gel. The allocated gel was first used to lubricate a catheter that was inserted into the bladder to measure the postvoid residual volume. After removal of the catheter, a cotton swab, coated with the same allocated gel, was advanced to the urethrovesical junction until resistance was felt. The angle of the swab with the horizontal plane was measured at rest and with Valsalva maneuver. Relevant baseline characteristics and the Wong-Baker FACES pain scores (where 0 is for no pain and 5 for worst pain) were compared. After randomization, lidocaine and the plain aqueous gel arms consisted of 69 and 68 women, respectively. Baseline characteristics of the groups were similar. Significantly fewer women in the lidocaine group (62.3%) reported any pain than those allocated to plain aqueous gel (80.9%) (odds ratio 0.39, 95% confidence interval 0.18-0.85). The median pain score was significantly lower in the lidocaine group (1, range 0-5) compared with 2 (range 0-4), P<.001). When compared with plain aqueous gel, 2% lidocaine jelly significantly reduces pain perception during evaluation of postvoid residual volume and the Q-tip test. I. Output:
{'conditions': 'Pain', 'interventions': 'Drug: 2% Lidocaine jelly|Drug: Plain aqueous gel'}
