Proceeding pro se and in fomia pauper-is (“IFP”), Dewight Vaughn McBride, Sr., Texas prisoner # 1337667, filed a 42 U.S.C. § 1983 complaint contending that the defendants were negligent in failing to treat him properly for diarrhea. After reviewing medical records and a Martinez report submitted by the Texas Attorney General’s Office, the district court dismissed for failure state a claim and as frivolous. See Martinez v. Aaron, 570 F.2d 317 (10th Cir. 1978).

McBride’s appellate brief consists of two pages. His argument section had only one sentence: “This Court has a duty to insure that prisoners are properly cared for as the standards of constitutional magnitude dictates.” McBride does not challenge the magistrate judge’s lengthy reasons for concluding that he failed to allege an Eighth Amendment deliberate-indifference claim and that Dr. Murray and Warden Rupert were not liable as supervisors or that the retaliation claim against Dr. Wright was frivolous.

Where an appellant fails to identify any error in the district court’s analysis, it is the same as if he had not appealed. Brinkmann v. Dallas Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Although pro se briefs are afforded liberal construction, Haines v. Kerner, 404 U.S. 519, 520, 92 S.Ct. 594, 30 L.Ed.2d 652 (1972), even pro se litigants must brief *327 arguments to preserve them. Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993). McBride has abandoned any challenge to the judgment. See Brinkmann, 813 F.2d at 748.

Because the appeal is without arguable merit and is frivolous, see Howard v. King, 707 F.2d 215, 220 (5th Cir. 1983), it is DISMISSED. See 5th Cir. R. 42.2. This dismissal counts as a strike under 28 U.S.C. § 1915(g), as does the district court’s dismissal. See Adepegba v. Hammons, 103 F.3d 383, 387-88 (5th Cir. 1996). We caution McBride that if he accumulates three strikes, he will not be permitted to proceed IFP in any civil action or appeal filed while incarcerated or detained in any facility unless he is under imminent danger of serious physical injury. See § 1915(g).
